    I have been experiencing missing spaces in the yellow channel nozzle checks since the printer  arrived less than 3 weeks ago.  After repeated head cleanings of the yellow/grey channel and one heavy cleaning, I decided to call Epson Pro Support. I told him that  missing the nozzle will clear after head cleanings and sometimes after printing, but the missing spaces in the nozzle returns the next day.  I was told that this should not be happening and that a technician would come out and switch out the printhead if needed. The technician who arrived was convinced that the missing nozzle was due to air in the lines, so he did another initial purge of all the inks and did not replace the printhead which had been sent to my house.  This required 3 visits because he didn’t have the replacement ink during his first visit, and didn’t have a replacement maintenance tank on the second visit. On the third visit he did a second initial purge of all the inks. Following this purge the nozzle check was clear.  I was hopeful, but unfortunately  the next day and the day after the missing in the yellow channel returned during the nozzle check. I called the Epson Pro Support line again and requested a print head replacement, but was told they were on backorder.  The second technician came out to see how he could help, although he didn’t have the replacement parts needed.  He was extremely helpful and spent several hours checking the printer with his laptop program, doing a unidirectional head alignment, and printing test prints.  Everything else looked good and he too was convinced that the problem was air in the lines. He assured me that it sometimes takes a month for the printer to clear all the air in the lines.  The nozzle check was good for a couple of days but has returned again.  Although there are less missing lines in the yellow channel, one line continues to show missing spaces.  It is always the same line in the nozzle check.  My question is this: Does it make sense that the air is always in the same nozzle, or is this a problem with the printhead?  Any thoughts or suggestions would be appreciated.  The technician will be returning to pick up the parts that were shipped to my house this coming week and I would like to resolve this issue.

    Marta, several aspects of this account raise questions. Firstly, it would be good to understand why air would get into the lines so soon after the printer arrived. My understanding is that there should be no air in the lines from the factory onward. Secondly, my understanding is that a channel pair can be purged without purging all the channels (I’ve seen this done on an Epson 4900), so it’s not clear why the technician purged all the channels. Seems wasteful. Thirdly, if a printhead had already been delivered to your house, why did the question of a back-order even arise? Fourthly, I don’t understand this story about needing a month to clear all the air from the lines. It is the first I hear of this and I haven’t heard of a brand-new Epson professional printer needing ANY such time. As I said, I don’t believe there is supposed to be air in the lines period. Fifthly, if it is always the same line in the nozzle check as you say, I don’t understand why the technicians haven’t concluded there is a head problem. Usually, as far as I have been made to understand, if missing nozzles remain in the same place time after time, it indicates the likelihood of a head malfunction. Before a technician arrives at your house to take back anything, I recommend that you have a further discussion with a senior tech support person in Epson ProGraphics telling that person very precisely what is going on, and asking that the technician be instructed to do the needful, as successive purging and cleaning have not resolved it.

    Sounds not dissimilar from the problem I had with my first 7500. On delivery, only PK and MK worked at all. An Epson engineer spent a day doing various things but not changing the printhead, after which the test page was fine. It stayed fine for a week or two but I then began to get various combinations of blocked nozzles. The head was duly changed but the engineer couldn’t get the new head to prime well at all. I rejected the printer, giving the dealer the option of refund or replace: he chose refund. I bought another from a different dealer and it’s worked very well from the outset.

    Mark, thank you for your reply.  I will call Epson Pro tomorrow morning as they are not available during the weekend.  The printhead was returned by the first technician because he decided that the problem was solved.  When I called back to report that the same problem had returned, the printhead was on backorder.  They sent other parts that might need to be replaced.

    Jeremy, thank you for your reply.  I’m horrified to hear about your experience with the 7500.  I hope that I do not have the same problem you had with the printhead replacement.
