hp l28500 ... 81:10 upon initialization

[MonsterBabyBLN]

new thread for this:
I am pretty desperate right now.
I have fixed this ISS problem where the printer would throw th 1:02:10 error...
but ever since.. initialization goes up to 95%.. and then the printer moves the drive roller fast forward a bit and swallows and stops with that error.
First I thought it was a hardware problem. something stuck.. I ve had funny noises before going forward never backwards..
I took all the gears off on the right side and cleaned and back together.
When I run the drive roller test.. the roller moves a little bit.. but the system says it didnt!

maybe some sensor is the problem ?.. I exchanged the motors.. no fix.

any advice ?

My bet is you disconnected or messed with the encoder while doing the ISS.

 

[MonsterBabyBLN]

You mean the encoder strip?
Or that disc that I have only heard of so far?

 

[balstestrat]

Disc. I recommend to once again open the manual read about it.

Good morning Balstestrat..
I checked the left side of the drive roller where the disc is.. but I cannot see how I could have messed up anything with it ?
I never opened the left side. when exchanging the ISS there is no way to touch anything as its covered.

I did turn the drive roller by hand when I took out the roller motor.. I didnt change the mounting. just exchanged the motor.
could anything "disallign" the encoder ?

funny thing is.. when I boot up the printer.. it does the whole initilazition now 100% and then while doing the INK initilization.. it moves the roller and stops ?
thats not a point when it sould move the roller I suppose?

I just realized the problem occured BEFORE I messed with the drive roller or the motor..
ever since I exchanged the ISS and the HDD..

so when I do the Drive Roller test.. 2.2 from the service menu,
I can see that it moves freely.. but the message displayed is: no movement!.. the consequence is he tells me Motor Error.. but its moving.. so obviously a sensor problem?

what would you do?

I'm saying this for the 2nd time now. I bet you disconnected the encoder sensor, hurt the cable or something. It's right next to the ISS.
It's not reading the encoder that's why it's telling you that.

Swap the sensor board and cable from your 2nd unit if you can't find anything else.

close call **
when exchanging the print mech.. I missed to reconnect the power for the sensor..
