torquer moves slightly and makes a noise. With the power off there
should be 88 ohms between J17-1 and J17-2, and neither should
have continuity to ground.
Remove the module and inspect the tray, the D-roll and the gear
train. Make sure the gear train is meshing with the drive gear at the
bottom of the printer. Check all mechanical areas and electrical con-
nections.
The Print Test with the RIP Board Removed can be run from the sec-
ond tray by disconnecting J14 and shorting J14-2 to J17-1.
Paper Feed Problem, Dual Rear Feeder
Run the diagnostics Paper Feed for Feeder 1 and Feeder 2.
Machine Level Information:
Early level printers do not support the Dual Rear Feeder without an
upgrade. If the feeder is not being recognized by the printer, print the
Print Menus test page and make sure the "Base" code level is at
least 32.00, and the "Engine" code level is at least 43.42.
On the early machines engine board connector J5 is wired differ-
ently. These machines require the J5/J10 external adapter box in
order to support the Dual Rear Feeder. On the Print Menus test
page, machines which require the adapter have an "Engine Card" of
12 or 16; machines not requiring the adapter have 12 A or 16 A.
Upgrade kits containing code upgrades and the adapter box are
available through normal marketing channels.
No paper feed: If the Dual Rear Feeder is recognized by the printer,
Feeder 1 (front tray) and Feeder 2 (rear tray) will be shown on the
Paper Source menu and on the diagnostics Paper Feed Test menu.
If it is not, check the printer code levels (see Note above) and test
the torquer.
J5-8 and J5-10 are inaccessible. J5-8 may be measured on test
point RXD and J5-10 may be measured on test point TXD.
