Epson Stylus Pro 7900 /7890 Series: Repairman mode

[@jailpinha3505]

I have an Epson 9700 and it turns the panel on and off and two screens are lit. the printer does nothing. what would it be?

[@squareglow]

I had a maintenance tank replacement flash pop up and prevented me from anything else. This bypassed it. Now how to unlock the print head…..

Hi.. how to fix error: maintenance request code 4000. Refer to manual.

Have you ever had an issue with the printer not pressurizing for the cartridges?! It won't even pick up my carts

I have a ca11main board with 7900 firmware on my 9890... it complains that orange and green inks aren't detectable... how can I disable compatibility check when flashing a 9890 firmware?

Did you ever get a response on this?

Is there a fix for the error 1536 on the 7890 or is it bet to get a new printer

[@HangryMuscle]

I would look up the user manual, it has a list of the error codes and what to do to fix them. Idk man, only you can decide that.

Description:Pressurizing reset error The pressurizing cannot be reset. The Pressure Sensor remains on, even after the pressurizing has been reset. Remedy:Replace the Pressurizing Unit.
