Hi everyone. I'm new here.
Please excuse if I ask any questions which have been answered already in other posts or threads I couldn't find after some searching here.
I came here because I found Erics report on his Epson 7900.
I have an Epson 4900, three years old. It had the "usual" clogs after little more than one year, and I was able to persuade Epson to exchange the printhead on guarantee. The printer worked quite well, but a couple of days ago, the clogs appeared again and the printhaed finally died:
At first, I got the error massage "Call for Servive Code 131B", which disappeared after turning off and on the printer again. However, the black and subsequently the LK lost more and more dots with every try.
Then, finally, the printer turned to the error message "fatal error 1A39" and stopped working.
I changed the printhead - after having found Erics thread here and his great video on replacing the printhaed in his 7900. Thanks a lot!
Changing the printhead wasn't too difficult. I did an ink eject twive, then started to replace the head, and everything worked well. Or, nearly so - at first. Then...
The puzzling thing is: The printer works, and after two or three normal cleanings and an exchange of the almost empty MK cartridge, the nozzle test was ecellent, no missing dots.
I changed to PK, and there was no black at all. Changing back to MK: no black. The LK had some spaces in the nozzle check but finally came back.
After reading through this thread and some other posts, I'm wondering whether its the damper unit. Any ideas?
