HP T1100 Design Jet / Error 81:01

HP Recommended
HP T1100 Design Jet
Microsoft Windows 10 (32-bit)

My HP design Jet T1100 is giving error message 81:01 stating possible paper jam and the screen is locked on this message and I can't get any selections to respond.  I just purchased the unit and was attempting to load paper.  When I first powered it up I got message ink has expired, I ordered ink / printheads and at this time I've installed ink only.  Installing the ink satified the issue then I attempted to load paper.


I loaded 24" roll paper and inserted paper until i got the beep tone but the unit didn't grab the paper and complet the loading process.  The screen then asked if sheet or roll and I select roll.  it insturcted me to raise the lever and I did and at that point i maunally fed the paper througe and closed lever.  


Now Im getting the error message 81:01 and my screen is locked.  I've unpluged & turned off the unit but when I try to power back up it goes through start up then the error message appears.  I have removed paper and checked but there are not torn piecse left in the unit.


Along with the screen being locked up,   the red light is on in lieu of the green & the power button is flashing

You need to clear the paper out and then restart the printer.


System Error: 81:YZ
Problem with paper advance.
Corrective Action: Try the following:
􀂄 Open the Window and check for any visible obstacles restricting the
movement of the Drive Roller. If there is a wrinkled mass of media inside
the paper path, lift the Pinchwheels (using the Media Lever) and clear the
􀂄 Perform the Media Drive diagnostic test to troubleshoot the problem
further ⇒ Page 4-18.
􀂄 If the printer has a 44 inch scan axis (and a Rewinder), perform the
Rewinder diagnostic test to troubleshoot the problem further ⇒ Page 4-
􀂄 Check the connections on the Main PCA; the Media Advance Drive is
connected to the connector labeled Paper Motor.
􀂄 If the System Error continues, replace the Media Advance Driver ⇒ Page


Do a google search for the service manual and download as you will need it to perform tests.
