*QUICK FIX* HP LaserJet M451 M375 CM2320 error 59.C0, 59.co, continuous cycling, calibrates forever

[@juhench]

Thank you so much! This brought our HP LaserJet Pro 400 color MFP M475 back to life. I also had the error 59.C0 and repeated calibration. This printer has a scanner on top, but one can access the respective solenoid like this: Open the side cover, 3 screws, one back, two on side bottom / Slide cover backward, pull off (without force). / remove all connectors from the mainboard (with the ethernet socket) and, if installed, fax module. Then unscrew the metal plate below the mainboard; there are about 10 screws, one of which on the backside. One can move a black plastic part a bit to turn the lowest screw on the back. / The cogwheel and solenoid with the metal lever are visible just a few centimeters behind the position of the mainboard. I then applied the sticker (I used electrical insulation PVC tape). After re-assembling, I made many printouts (on used paper, of course) non of which failed! Congrats for this fantastic fix.

[@FieldServiceTechBusiness]

That is great! glad it worked on your M475! Thanks for the detailed instructions on your fix.

[@juhench]

@@FieldServiceTechBusiness I have to say thanks. I know how much work it is figuring these things out and - in addition - sharing them as a video. Without your hint, I would have been on the wrong track. I had read somewhere else that the error is induced by too high a force / current on the motor that transports the transfer foil. I would never have suspected the solenoid was causing the problem. Mine is a printer rescued from the garbage several years ago; it just got a new life - again. Good for the environment and for the wallet.

@@juhench Unreal!!! I cannot believe this worked, I had just about given up on this printer! Thank you! I cleaned up the area and folded a tiny piece of paper so it wouldn't stick... Worked perfect.

Thanks for the video and thanks for the comment about the MFP model, I've got an M475dn here. It's not everyday a KZbin comment is genuinely helpful. At first I thought I had a pickup issue, so I went for the pickup assembly solenoid, which was indeed a little bit sticky, but this did not solve the problem. The solenoid you pointed out was the actual culprit. Disassembling the pickup assembly was a real pain too, but at least now that I took care of both solenoids I hope I won't have to do it in the future… If only the service manual wasn't missing half of the useful info.

[@jayjoans186]

You sir, have my undying respect and admiration for posting this video. I have an HP CP2025 and this information you provided and explanation was OUTSTANDING. In the case of the 2025 like I have, the dark grey side piece has a piece of plastic overhanging the offending solenoid, making it impossible to reach it from the top without taking off the whole side piece which has wires running across it. For you other 2025 owners out there, you don't need to remove this whole side piece. A couple of side cutters will do and just cut the plastic square that's in your way above it for easy access. (I read someone used a Dremel tool, but that will spew all sorts of cuttings all over the innards, do not recommend) The cut will be covered by the top piece when you reassemble. I used this vloggers suggestion and cut an Avery label 30mm x 15mm and folded it in half, slid that right into the spot and everything works great. THANK YOU.

[@FieldServiceTechBusiness]

I really appreciate your comment and feedback. Glad it worked out for you! Thank you for your added tips on the procedure.

[@walterselders3681]

HP CM2320FXI MCP. It took me a while to identify the problem. It starts with printing some pages and then keeps turning and clicking without producing any further prints or not picking up any paper at all (trays or manual). You start by suspecting the pick-up rollers but then finaly the 59.C0 starts showing. I then found your video! Perfectly explaining and showing how/what to dismantle, then clearly showing the problem and the solution (workaround). I just finished doing all that on my HP CM2320FXI MCP and the problem is solved. Wonderful, thank you very much.

Nice work!

[@JonathanSeni]

Bought LaserJet CP1525n color 10 years ago and never used it after it's first toner. Got a need for a printer and found it switching on so I bought toner and tried few copies, all test pages were printed ok, but after few prints I realize the printer took a lot longer to print any document, then yesterday I got the error code 59.c0. Look up online and this is the first place I found a solution. Thank you so much, when I get time I'll try to do this quick fix.

[@Вася-ш3щ]

And how is it going?

[@thewave2025]

Worked on my CM2320FXI... had to reach deep but your video showed me where to place the tape/paper... thank you!

[@DerpaDerpaDooo]

Thank you sir, I just changed the pick roller thinking that might fix my issue and came across your video

[@FieldServiceTechBusiness]

[@binhdinh5979]

Thank you very much because your method helped me repair my Laser Jet Pro 400 Color M451dn printer successfully and now it no longer runs forever without printing anything.

[@FieldServiceTechBusiness]

Super glad it helped! No more "running and cycling forever"!

[@christianabrahams5227]

Fix also works for CM2320, just inserted a little sticker as shown. Perfect solution, saving me a lot of money. Opening of the CM2320 is almost the same, see other videos on the net, then proceed like shown in this one. THANK YOU, whom ever you are. As semiconductors are badly available currently, a new printer would have cost a lot and I like mine and still have lots of toner. Again thank you.

[@thewave2025]

I have a CM2320FXI that I am going to "operate" on... if you can post pictures or video on opening that model and showing the location of solenoid, I'd appreciate it.

[@ErikCarlsonUK]

OMG, you just got me out of a hole with this. In my case i didn't use the sticky method, i just cleaned the sticky off with isopropanol. Thank you so much!

[@FieldServiceTechBusiness]

Glad I could help!

[@ValdikSS2]

You still better to put something in between. The sponge is there for a reason, without it the metal plate could still stick to the solenoid because it is an electromagnet as well.

[@EdFhvn]

THANK YOU! THANK YOU! THANK YOU! A simple (relatively) fix saved a $700 laser printer when every other site (including HP's own community forum) said the 50.20 error meant the unit had to be replaced. None even offered the solution to replace the solenoid... which I probably couldn't do. A 1/2" piece of and address label and the problem was solved. FOOTNOTE: I didn't take as much of the printer apart as you did. I only removed the screws on the back; the two screws holding the top then unsnapped the top and had all the access I needed. Didn't remove the sides or the toner tray. Plus I only used a one-sided label as opposed to folding it in half and sliding it in between. I didn't have as much room on mine as was showing on yours, but the tweezers slid it into place and it stuck and the solenoid opens and closed cleanly. I could tell by the sound it made when it started up it was going to work. Got into the menu; printed a test sheet and it worked like it did since day one.... And day one was several years ago. Thanks again.

[@FieldServiceTechBusiness]

excellent! glad it worked out for you.

[@longlifeprinters9]

Fantastic, this works great on millions of HP laser printers. Almost no solenoid ever needs to be replaced, just get the gooy, sticky pad to be covered with that folded in half sticker or label.

[@FieldServiceTechBusiness]

Yes, sounds like you did this before.

[@goldtaka]

Thank you very much! You kept a printer out of the landfill and it was a fun project to take it apart.

[@FieldServiceTechBusiness]

[@ryanhunter9757]

Holy guacamole!! Thank you so much for making this video!! I have an M375 that was having this problem. I stuck a screwdriver in there covered with a dry wipe dipped in acohol and dcrubbed all the glue off and it work well too!! This 375 is much harder to take apart because of the scanner unit, so I figured I'd go for a more permanent fix. Thank so very much for making this video you just saved me hundreds of dollars.

[@FieldServiceTechBusiness]

Glad it worked! Great job on your fix!

[@MrLifestyleSpeaks]

THANK YOU! With this time consuming yet inexpensive (aka "FREE") fix, I am hopeful that I can get another 10 years out of my favorite printer. Btw, just using a strip of paper (1 cm x 4 cm) folded into a V shape worked perfectly for me!

[@FieldServiceTechBusiness]

Great!

[@miengtan]

Thank you!!!. It's so simple, I can't believe it worked. I also used alcohol with small piece of paper towel wrapped around a toothpick and tape on one end. Just wipped the tip around the area to clean it.

[@FieldServiceTechBusiness]

Glad you were able to find a solution! Good job

[@GarrettHunter8]

Thank you. I had the same forever cycling and this solved my problem for now. You rock!

[@FieldServiceTechBusiness]

Great to hear you got it working! Yessah!

[@zerafilmcz]

Thank you very much. It worked also for my CP2025. There is not so nice acces after same disassembly and I didn't want to take whole printer apart. So I just needed to cut 5 by 5 cm of inner upper plastic cover in order to comfortly apply sticker. Now it works as new.

[@die871]

Worked great! Thank you for saving my HP printer.

[@diamantis80]

Thank you so much for the tip! I have a different model, but it worked fine! I couldn't reach it well, so I was only able to put a piece of scotch tape, that won't hold for too long. But at least now I know what the problem is and next time I will disassembly it more and I'll do a better fix.

[@FieldServiceTechBusiness]

@@diamantis80 Glad it helped!

Thnx mate! Helped me solved the problem!! Would have never known without you. Just don't understand why there are more screws on my desk instead of in the printer.. Have to sort that One out..

[@EdFhvn]

I know the feeling. Once I started to take the printer apart, I realized I was never going to remember them all, so I video taped my deconstruction so I could remember where all the screws needed to be returned to.

[@herbrjohnson]

Thanks for this video. My CM2320 stopped feeding paper after changing a toner cart; I thought I broke the printer. Some Web search on continuous cycling led to "sticky solenoid" and then your video. The paper fix is the same one I learned for the HP LaserJet II decades ago. Why do printers still have glued rubber deadeners?

[@deem3767]

Thank you very much for sharing this. A little piece of black pvc electrical tape (like you suggested) sorted the problem. Much appreciated.

[@FieldServiceTechBusiness]

Great ! Glad it worked out!

[@pylorih.5504]

Thanks, very helpful video. I read in some comments that it would work as well to just clean the metal. I tried this, but it did not work. So you really need some kind of label or felt to cover the metal from the solenoid. Maybe this helps someone, too.

[@FieldServiceTechBusiness]

Thank you for the feedback. I too as well had the same problem with just cleaning the metal plates. When there is only "metal to metal" there seems to be a small magnetic residual charge that keeps the plates sticking together. An insulation such like a label or sticker as you have used prevents that. Thanks again.

[@williamwebb2042]

A friend gave me his venerable CP2025 when it stopped printing. Since it was not jamming and the symtoms were the same off either feeder, I was quickly convinced that it was the solenoid in your video. Sucess! I am now printing. One thing however, in your video you don't show the black plastic frame on the right side being removed. I was able to pry it out of the way a little and that was enough to proceed with great difficulty. Can you address the removal or shifting of the black frame? P.s. I cleaned the slenoid assembly a bit my scrubbing with a dental pick and a trimmed down emmery board. I inserted folded kapton tape for the repair.

[@bradkaral1188]

How did you clean the plates before applying the label? Other people said to to use a cotton swab with alcohol or similar, but I can't manage to fit a swab in there-the space is too tight.

[@FieldServiceTechBusiness]

You can try to clean them out, I did so a few times myself, but found there was no need to do so if you place two sheets of labels in the slot (non-stick sides against each other and sticky sides against the plates). Typically covering the old and worn adhesive on each of the plates.

[@bradkaral1188]

I don't know how I'm going to manage get it in there, but I'll try. Thanks.

Welcome!

[@LogiForce86]

Is it the same on a CP1515N? Would a fix be superglueing a piece of bicycle innertube in the foam's place to prevent the piece and main body sticking? Also I have a demagnitizer for my tape, and should I use it on the plate?

[@FieldServiceTechBusiness]

These are great suggestions, test and see if it'll work. My experience with alternate materials vary, too much thickness may sometimes cause issues, the same with it being too thin.

[@LogiForce86]

@FieldServiceTechBusiness I already did, and inner tubes of bicycles are about 1mm thick, so perfect. Works great but I thick I misaligned some gears because tray 1 doesn't feed in far enough and throws an error. You wouldn't happen to know which gears operate tray 1 per chance? Otherwise I need to disassemble it all again and check and double check.

[@FieldServiceTechBusiness]

@@LogiForce86the material may be too thick which causes the pawl of the solenoid to not clear the notch in the collar when engaged. Might need to try another less thick material.

[@joshymcdaniel9233]

Any idea where it’s located on the HP M251nw I’ve got all 3 covers off but in that area you are in I don’t see solenoid 😡 is it in different location on the m251?

[@FieldServiceTechBusiness]

Yes m251 is a different layout, hoping to post a video on that one soon, sorry.

[@jeonglee6411]

I have 12 year old CM2320nf and since I start use it for 12 years I never had any issues. But recently all of sudden, my printer does not feed paper from any tray and continuously running prints or copy operation without paper feeding. To stop this malfunctioning, I need to unplug the AC cord. And I didn't have the error code "59.C0" with the latest firmware. I have the latest firmware so, there was no firmware updates necessary at HP support site. So, this video was very help to fix my printer. in my case when I fix the solenoid the problem was not resolved. So I changed the Pick-up roller and the Separation roller together. And then my printer starts work again as brand new printer!.(Lots of videos in you tube for the roller changes). Thank you so much to providing this video!

[@absoluteeventsandentertain3692]

I have an HP LaserJet 500 m551 printer, and I have the error code 59.00.CO as well, It is hard to reach as a non-professional, I was just trying by watching these videos and following instructions which I did base on the nearest model printer that matches mine, I can't take it out based on the location, I was watching a video until he stops there and use a method and took out the entire bracket that holds the gears and solenoid, so I didn't see the last part how he did it, so I came up with my own method to get rid of the sticky padded piece, " but It wasn't sticking at all, but I use a long needle to scrapped it off, it moves free, been doing so before i assume it was sticking, base on the test i gave it to check if it was really sticking, I close back up the machine which was the hardest part, as I couldn't remember the step I took, I put in the screws in the holes that I saw empty and so far, it holds together, yet I still have about 6 screws leave back, After I manage to do so, I turn on the printer to now see fuser error, but it hardly comes back, but the error code 59.00.CO returns, yet my solenoid has nothing to stick on to cause a delay...what can I now do to solve this issue.
