Designjet Z3100 44" Q6659A. error 48:00

HP Recommended

I am fixing this printer for over 3 weeks now & it kept show different error codes & driving me nuts.


I bought this printer from a Miami recycle  store & delived to my door. before I touch this printerit had ink missing problem,  then belt was horribly bad.  inks dropping to error, I was able to print a diagnostic image & identify
the missing inks..7 colors were missing.....


So I complete clean the whole printer &   inks, ink  marks & used an injector to suck out all airs....all

were super nice clean . Then I replaced the belt.

then when I started it & got 86:01 error, paper jam... no paper loaded & alone without any connection to PC.

I got stuck for 2 weeks & could not pass this error, I swapped out 2 formatter boards & print mech board.

same old, same old.


Yesterday morning I checked the trailing cables to the mainboard & found #1 cable, the third pin was up tiny

& I flatten it & inserted onto mainboard.


Power up & it past 86:01 & went few more seconds longer, then when service station tried to move to left &

It shown  48:00   error.... no matter how I did, ajust belt tentions... clean silver rod, encorder strip, lubrication etc

etc, whatever I could think might woth to try....    same old , same old.


I searched this board & found one topic related to this problem & David mentioned the scan axis motor check

on service mode.


So I did a test on scan axis & almost to the end :

moving prs to high  >>>>  error 48:00 came right up .


what does it mean ?   scan axis motor bad ??    all were perfect till I changed the belt....


Thanks in advance for your kind help.....

I replaced the scan axis motor with another one  ( I took it from an old junk 24" Z3100 ) 

& now printer past the previous error 86:01    48:00..  now it prompting me for inks & printheads........


if you ever encounter these errors.... try above.
