Troubleshooting the 1611 and 1711 folding machines
When machine is turned on only a humming noise can be heard.
Check the belt and pulley under the operator side cover
Paper will not feed into the machine
Check for paper under the bridge (the metal piece between the feed wheel
and fold rollers). Use a rewards card, letter opener, or another thin stick object to
clear any paper from this area.
Check the feed wheel to see if it is turning. If it is not turning check the set
screws on the feed wheel, the pulley and belt under the non-operator side cover.
Jamming
Clean the fold rollers. Dirty rollers can cause jamming.
Check for obstructions in the machine.
Check placement of the second fold table with the manual.
