Are you printing on low or high settings?, If on high try printing on low.

 

[Redz Signs Inc.]

chicago what are you refering to as far as high or low settings

 

[MikePro]

he's referring to head height, most likely

i'd say communication error.
1) power-down your printer, unplug from wall, and hit the green button to discharge any stored electricity.
2) swap the two ribbon cables for the black head at the slider board
3) power-up and run a test draw
if the problem jumps to the other channel, you might have board issues.
if the problem persists, power-down again, put the ribbon cables back to original place, and pull the bad channel's ribbon out from the printhead and re-seat it.
power-up and test draw again. (if this corrects the issue, it just meant that you had a bad connection. if it persists, your head might be going bad)

Black head

How old is the head?

 

[Redz Signs Inc.]

not sure as to how old the head is.... mabe 3 to 4 yrs and for it to drop out like that is really weird expecially the next day ...i might have to go with bad bach of ink .....but im still not sure

i had a head do that once and it cleared up. i blamed it on some heavy ink or something coming down the line.

i'd do like mike pro suggested. at least with a data swap, you can start eliminating the issue. also, if you swap black dampers, does the issue go to the other side of that head?

 

[Redz Signs Inc.]

i havent tried to swap the dampers never thought of that ..

i will have to give it a try thanks for the quick responce i really appreciate it .

 

[Redz Signs Inc.]

well at it sits now all of a sudden half of the channel came back on its own i will post pics as it get better ...

 

[Redz Signs Inc.]

Ok attached is the same head that was causing all the problems that most said the head was shot.... i did nothing no cleanings just kept printing and as you can see its starting to come back. these stupid head monkeys! need to leave me alone but here it is i thought i keep everyone posted.

 

[artbot]

when you did the data swap, what did the test render. did the magenta left side act up? or did the issue stay with the black head?

 

[Redz Signs Inc.]

acually i switched the cables and did a test print and nothing printed but it went threw the cycle as it was going to print.... weird... but it put it all back together andleft it alone and printed everyday even something stupid andthis is what happened it started getting better it took about2 days and this is how much ithas progressed from the inital pictures. as fast as it got screwed up is howfast it comming back....crazy right?

 

[artbot]

to me if you did the swap and it did nothing i figure the cables maybe weren't seated or ??? there should be no reason at all that the printer would even be aware electronically that the swap had occurred. i'd do it again just because it is the one procedure that will point to the head or boards or in some cases the ribbons. also you can do a "same head damper swap". put the right side damper on the left side and vice versa. that will give you a good read if you are having an ink/supply issue. my bet is that there is something wrong with the head if all else points to normal.

i mabe dident do the data swap correct. how is it that you do it correctly?
