Actions already done, performed by me (I replaced previously belt, HD, and have service manual):
1. Lubricate with oil from the maintenance kit, cleaned encoder strip
2. Replaced belt as older one was already bad, clean, lubricate, cleaned encoder strip
3. Replaced tensioner assembly (problem not solved with these actions)
4. Replaced trailing cable (older became damaged after some servicing)
5. Replaced motor (machine gave system error at startup, then printhead path again)
6. Released tension on the belt as possible cause, machine started up ok, did pinthead
calibration successfully and started print normally. Scan axis test ok
-> 217 193
<- 216 192
7. Machine printed ok about 50 A1 prints without any error, smooth and silent movement from print heads, normal quality. Even a system error disappeared (Thought problem was finally solved)
8. Error came again (check printhead path (1)), Scan axis test ok, service station calibration ok, system error sometimes at 5% startup (checked trailing cable and all
connections – ok, checked printhead movement - ok). Did printhead calibration, failed once (screen became black) and did successfully at 2nd trial. Tried to print again, error came again.
9. as far as I read manuals, only thing I didn’t already done was change motherboard.
10. With all this information, I’d like to hear from a specialist, what steps should i do
(before ordering a new motherboard) to diagnose or solve the problem.
Please help me out of this as we have lots of work to print, many thanks for your concern.

I will go thru these 2 steps before getting a new motherboard.
Please advise on power supply reading.

Thanks for the great information regarding calibration of the printhead height. I was having the same errors after replacing the belt on my DesignJet 5500PS recently. I got the height adjustment tool and found that I was having scraping in a couple of spots. I made the adjustment, tightened the screws and re-checked the height again. I was pretty sure this was the problem, but had to wait a while to be able to test it.
The darn printer wouldn't boot after making the adjustments, I was getting a boot failure with error code: 1f50007 Hard Disk Failure. After searching the forum for this new error, I tested the 12V leads to the hard drive and found out the power supply was bad (24V and 36V also were dead). After replacing the power supply, the hard drive booted fine and it seems the printer is printing without a problem again.
I did have warnings about the power supply as the hard drive failure message came up a few times before, but went away when I switched the power off and back on. I guess the power supply was getting glitchy.

I know this thread is very old, and so are these printers. but I need help. Im getting error 2 at start of print. I have replaced the belt, lubed the rails, cleaned the encoder strip, adjusted the carriage height, belt moves smooth. PLEASE help me with something to try or check. I was getting it and I was able to get a few prints after turing in the height screw a few turns but then nothing. another time i was able to place a dot at the other side of my media so i wouldnt print immediately and that worked for a while. now nothing.. reinstalling firmware next.

here is a update. i checked the tensioner and seems like screw is all the way out. updated firmware and hit print. it started printing but before it was about a inch into the print it stopped at the normal point where it says to check printhead path with error 2 still.

Im using the height tool I have it as low as i possibly can without it scraping. it seems all the lines are there on the encoder strip still. any suggestions for cleaning it better?

You have to make sure that the first set shown goes over the pulley and should have that type of lines for the complete width of the plotter as you move the carriage from left to right. The same for the second set which should be over the motor shaft. If you move the carriage from one end to the other and the lines that should be over the pulley are over the motor shaft or vice versa, then the belt was not installed correctly and can cause path issues.
