Dear all,
I red a lot of articles in this forum about variouse problems with the Epson 7900 printer. I own one myself and I keep having problems with it. Besides I want to mention, that the printing quality is excellent, which is why I sill have this printer active.
My printer used to make cleanings at random times, even if all nozzles where perfectly clean (due to a nozzleprint). I am in contact with Epson Support in Germany since months, I have been sent two special Firmware versions, which were supposed to solve the problem, Epson even changed the whole Cleaningsection of the printer with a "special adopted" version. But I still keep having these problems that cost me so much ink, time and money.
Can anyone reproduce this phenomenoms (these are the ones I can reproduce, the other ones are random):
- When switching from MK to PK oder PK to MK the process bar appears, goes from 0 to 100% them the printer reports "ready" again. When sending the next printjob or printing an nozzleprint from the printers menu, the printer starts a full cleaning every time. This cleaning will almost everytime clean black and light black. This even happens when I print an nozzleprint and have NO clogging at all and then switch black inks. According to Epson this is not normal and should not appear, well it does every time and pumps about 20-40ml ink into the maintainance tank.
- When I switching on the printer and print a nozzleprint from the printers menu and I find any clogging, I perform a standard cleaning or a cleaning of the affected pairs. Even if the light black ink had no clogging at all and was not one of the colors I selected to lean, it will be extensively cleaned every time (3-5% at 350ml cartridges). This is why my light black is at 18% while all other cartridges are at an average of 63%, and this is why I now always start the printer in maintainance mode to do a cleaning that will only clean what I say.
Please let me know if there are other printers with the same problems out there.
Well, Epson is going to change two other parts of my printer in about two weeks, we will see if this resolves these issues.
Thanks for your feedback!
