Hi all,
I have a problem and I’m running out of options, so I turn to you hoping you can give me some advice.
I have a 4800 that I have been using for prints and digital negatives with a P6 set with both PK and MK and gloss.
We try to print at least every week and up to a few weeks ago this went fine.
At that point I started to notice that the first ¼ inch and last ¼ inch of a print had some stripes if this part was midtones.
So I did a nozzle check with cleaning and noticed just a few blocks missing at the KCMY side.
I let the head soak on a lint free cloth with piezoflush overnight and did another nozzle check only to see that the problem had gotten worse.
Now there were a lot of blocks missing:
At this point I noticed that the ink in the cartridges was on the low side, so I put in more ink that I still had in cartridges from the 4900 that we used before and is totally dead.
When filling the cartridges I noticed that the cyan didn’t prime. I tried to suck out the air from the outlet, but nothing happened, so I ordered a new cyan cartridge.
The cartridge arrived this week, I transfered the ink and did two power cleanings from the printer maintenance menu.
It got even worse:
I thought that there could be air in the lines, so I just went ahead with an initial fill, to be sure that all lines were filled with ink.
To my big surprise and shock, this messed up everything:
By now the ink in the cartridges is below the minimum line, so I have to order new ink.
I also got cap replacements for the capping station and a spare flushing station, I figured I might as well replace these too.
I also got cleaning syringes that you connect to the head to force ink or cleaning fluid through them.
Before I order new ink and spend more money I would like to get your opinion.
What can be happening? What can be causing this problem?
How can I fix this?
I have seen in a video that you can disconnect the printing head to inspect it visually. Is it a good idea to clean the head manually?
Please help!
