  1. Re: L26500 (Latex 260) after replacing the belt get 79:04

    Thanks for your reply.

    I think I resolved it by the ol' remove all consumables--ink, printheads, and media--and reinsert them as requested by the printer. None were rejected upon reinsertion. ...
  2. L26500 (Latex 260) after replacing the belt get 79:04

    After replacing the belt on an L26500 (Latex 260) I get 79:04 right before it gets ready to print a test print. I think there MAY be a printhead problem that is the source, but not sure.

    I...
  3. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Now it seems like a phantom problem. ....the mid-section only scan has occurred once since I did this below--it will probably do it again. I will probably reinstall ALL the replacement boards just...
  4. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    I couldn't stand not knowing what specifically fixed it.


    I put the old main pca in, and "bingo", it scanned to black.


    So as best as I can tell it was indeed a bad main pca that caused the...
  5. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Thanks Kiran! ....At the admonition of Kiran to "erase parameter blocks", I had them erased again--I had done it already about 3 or 4 times. But this time it worked. I encountered no errors and it...
  6. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Well, dang! I replaced the main pca with a new main pca. At first, I scanned a drawing and it appeared in the preview--no black scan!!!! Yee haw!!!! There was a vertical line on the right...
  7. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    ....yes, I have the correct calibration sheet; however, it is a bit beat up with all the drive roller marks on it. I have successfully calibrated a 4200 with the 4500 calibration sheet. I was...
  8. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Hi, Kiran. Just want to confirm: For a "4200" scanner, you have a new driver board and new main pca? Right?

    I still have a 4200 scanner for which I inquired about 3 years ago about the 50-195...
  9. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    OK, Kiran. Thanks again very much.

    Yeah, I THINK PSU and driver board are OK. But I'm not 100%.

    I hope the main pca takes care of it. But am thinking for 55-203 I will have to replace...
  10. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    I responded to PM, but I found no evidence it was sent. Are they reviewed before sent? At any rate, I would like to have the main pca you described. Please let me know what you need. Again, I...
  11. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Thanks Kiran. Yes, I reseated all 3 camera cables to the main logic board, but that's all. I should reseat everything.

    So, you would start with a main logic board replacement? (But so far as...
  12. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Thanks, Kiran. Both lamps that I tried are lit, so they are getting power. Is the driver board just for driving the lamp? I don't know.

    Do you think this scanning to BLACK is a BAD driver...
  13. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    I was trying to get it to calibrate but again only got to 55-203 & 55-608. Well, now even before that it states that the calibration sheet is not recognized. It had worked a few months ago; and...
  14. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    OK, thanks. ....I tried calibrating. During vertical alignment Got 55-203. I guess a camera is not moving--bad motor or jammed or something. Dang!

    I'll run the scantests 6, 9, or 11. Boy,...
  15. Re: HP Designjet 4500 Scanner-after a while starts only scanning center one-third onl

    Hindsight: It seems that the scanner senses the top part of the drawing--the dome--as being the image to be scanned, so it simply scans the width of the dome plus a margin--the dome seems to be the...
  16. HP Designjet 4500 Scanner-after a while starts only scanning center one-third only

    Help. HP Designjet 4500 Scanner-after a while, several to many minutes, starts only scanning center one-third only (scan image attached), only between the 2 stitch wires apparently. (Maybe I...
  17. Re: L26500 or Latex 260 system error 24:10 broken bag error

    I ran the test for the curing system as well as all the heating and curing service tests. About the 1st 3 times, the curing RCCB breaker tripped. I got system error 14.08:00 at least the 1st time,...
  18. Re: L26500 or Latex 260 system error 24:10 broken bag error

    If there were a problem with the curing or drying circuits/controls, would it have thrown up a system error prior to requesting printheads? I would assume so.

    I know it threw up 14.05:00...
  19. Re: L26500 or Latex 260 system error 24:10 broken bag error

    ....I thought after the installation of new ISS boards that the printer would direct me to install set up printheads [also I had reset the EEROM back when I was struggling with the 50.1:11 error...
  20. Re: L26500 or Latex 260 system error 24:10 broken bag error

    I got the STS compatible cyan and black ink cartridges today; the old ones are deemed "faulty". I installed them. And it moved on to ask for the printheads.

    So now I am on to installing new...
  21. Re: L26500 or Latex 260 system error 24:10 broken bag error

    Thanks for ALL your input, Kiran.

    I would be hard pressed to find another L26500 or Latex 260 to try them in--the 2 faulty cartridges.

    I assume the mouse crapped-on upper ISS pca being damaged...
  22. Re: L26500 or Latex 260 system error 24:10 broken bag error

    Hmmm...I've never filed one. I could try that. Have just cleaned with alcohol.

    I weighed the black and cyan ink cartridges--34.6 ounces for black, 33.3 ounces for cyan. I suspect that both are...
  23. Re: L26500 or Latex 260 system error 24:10 broken bag error

    I replaced the ISS boards. It started the tubes priming process. "I was excited for a moment." But only got as far as "replace faulty ink cartridges": Black and Cyan (Could this be because...
  24. Re: L26500 or Latex 260 system error 24:10 broken bag error

    OK, I didn't think about the updating of the chip on the ink cartridge.

    Thanks.

    FWIW, I got a response from Tim Wert of LPS Computer about the approx. 4 year old ink sitting in the printer; he...
  25. Re: L26500 or Latex 260 system error 24:10 broken bag error

    I hope new cartridges can be used. I found myself thinking: Insert needle into tank and drain to less than 88%.

    I'll see. One step at a time.

    I'm just going to install the 2 - ISS pca's...
