epson 7800 print issues
« on: November 23, 2017, 03:51:17 pm »

Hi, I been using a 4800 for printing, but one of the slots in ink bay has stopped recognising the cartridges, tried many cartridges and replaced the sensor, but no joy :(
Picked up a 7800 which was supposed to have just a black channel out, when I tried doing some cleaning routines and a nozzle check/purge file print I was getting yellow in most channels?

I installed new dampers, cleaned up the head and tried again. This time I was getting nothing on test prints even after a power clean.

I decided to take the print head from the 4800 which was printing ok prior to ink bay issue and install it in the 7800 as they are the same print head.

Did a super sonic clean and am getting very little on test print and some odd patterns on purge file prints?

The prints are bad with lots of banding, but what is strange is that the channels do not seem to be printing the correct colours?

I am beginning to suspect there may be another issue causing this?

Any suggestions?

Thanks
