So, one of these machines is presenting a printing problem i cant seem to resolve yet, attached images show the error, NISSAN one is the bad one, the Ofice Depot one is how that same fuser prints on our machine, it looks dirty scanned but in reality it is just fine, i edited out some personal info for obvious reasons.
First time client called reported toner was loose and he could actually remove it from the paper with his finger, tried playing with the FIXTEMP setting on service menu, it was originally at 3 so i turned it up all the way up to 7, did a power cycle, and it didnt help.
Took the fuser unit to inspect it and pressure roller looks OK, fuser film looked a bit worn out so i decided to replace it with a brand new one, cleaned everything and applied fresh thermal grease.
4 days later problem came back, same dirty prints, toner is loose i could remove it with my finger, so this time i thought maybe the heating unit was done so i used the one we have for testing at the shop and it started printing fine... for a day and then AGAIN the same problem.
This time i took a whole fuser unit we have at the shop for testing and vacuum cleaned the dev assy in case toner was the problem, and took the original one back to try it on our machine, here it prints just fine, lines are perfect, no "swipe" defects, so i guess this rules out the heating unit, pressure roller and fuser film as the cause, fuser assy seems to be working just fine.
Im out of ideas, problem doesnt seem to be on the actual fuser unit, as i said ive tried with a different fuser combinations, tried with OEM toner and also generic one. everything works fine on our machine, but not on theirs, the only thing ive notices is that the right door feels a little loose, a couple times it even got stuck and had to use a screwdriver to open it, client also says in some days it james a lot on the fuser area, checking the jam list i see a few sensors throwing delay errors PS10 and PS13 being the ones with most.
any suggestion welcome.
