I have a Roland SP-300 (regrettably it seems) that was serviced a few days ago. The tech did a few print adjustments and serviced wipers and sponges. No big services just maintenance.
Test prints were fine from the plotter menu. We didn't print anything from the PC. I even asked what he thought of the machine as far as the heads, motor etc and he said from what he could see the machine was in terrific shape and unlikely would need anything for some time. It has only 600 hours on it after 7 yrs.
I went to do a job a few hours after he left and the black/cyan colors wouldn't print. I ran the machine through several cleanings and did a test print- no dice. It was late so I went to bed and talked to a tech the next day who had me go through procedures to test ink flow which we discovered it was passing through the head fine.
He told me he would have to set up an appointment to have someone come out because we had exhausted all electronic alignment possibilities and someone would have to physically inspect the machine. I heard nothing back but read that a fuse might be the culprit. After continuity testing I found that the f3 fuse was blown and I had it replaced. Now when the machine is powered up the fuse blows when it goes through the start up cycle.
I have checked all of the ribbon cables and cannot find a damaged, kinked or loose one. There seem to be no resistors blown on the main board or the head circuit board.
I know people are quick to jump to the conclusion that the head is bad but do you mean to tell me that minutes after a tech goes through the machine, gives it an A+ grade and tells me the heads look great, that one suddenly just died?
Any thoughts appreciated and is there anyway to check the cables to see if maybe one is bad? I am just amazed that this thing just up and died right after a service when it was adjusted and test printed beautifully.
