Epson 4880 new behaviour
2018-12-11 by goch@...
For those of you using an Epson 4880:
I have used a 4880 for many years. I have used Epson and MIS inks in various combinations.
Three times in the past I have installed "cleaning cartridges" and cleaned the heads. The cartridges were/are from China, and had resettable chips. I did not have any problems doing this, and leaving the printer overnight with the cartridges still installed (after doing a couple cleaning cycles), always produced perfect print-head checks.
Today I needed to use the cartridges again, since there was clogging that regular cleaning did not touch. This time, though, the printer would not accept the cartridges. It would recognize them, inform me that they were not genuine, and ask if I wanted to risk it. That is perfectly normal. But after I accepted the risk in proceeding it would tell me to load cartridges. The printer menu screen showed empty boxes for all of the cartridges, as though nothing were there.
After a while I gave up and reinstalled the ink cartridges. I have been using MIS Eboni, LB and LLB for at least two years, with Epson colours. The 4880 recognized them as not genuine etc. But after accepting the risk, the printer told me to load cartridges. This has *never* happened before with these cartridges.
Any idea what has happened?
I may be using a newish print driver on one of my computers, but I know for certain that I have *never* upgraded any firmware.
