Clearing Paper Jams; Feed Wheel Cleaning; Bushings And Folding Rollers - Martin Yale 1701 Instruction Manual

8. Remove (2) Philips pan head screws from the bearing blocks. Grasp each bearing block at the top edge and
lift it straight up from the machine (Fig. 18).

9. Clean the exposed rollers by spraying Martin Yale Roller Cleaner and
Rejuvenator onto a clean cloth and wiping until all contaminates are
removed. Turn the rollers with the large pulley to get all the roller surfaces
(Fig. 19). Alcohol or a mild soap and water solution may also be used.
Avoid getting cleaning solutions into the bearing surfaces. If the fold
rollers become glazed or shiny, it may be necessary to return them to a
dull luster by using a lightly abrasive non-metallic scouring pad. Never
use metal pads such as steel wool or sand paper, as the shavings
or grit will damage the roller and bearing surfaces.
10. If needed, apply a single drop of light machine oil to the inside of the
roller shafts next to the bearing block. Avoid over-oiling as it will seep
onto the roller surface and transfer to your paper.
Reassemble the folder by reversing steps 1 through 8. Care must be taken when re-installing the right cover and
control panel. Make certain the wires and ribbon cable are not pinched in the cover and are routed away
from the roller gears and paper stop drive belt!

5.2 Clearing Paper Jams

Use the following steps to clear a paper jam:
1. Disconnect power to the folder.
2. Remove the 1st and 2nd upper fold tables as described in section 4.1, step 4.
3. Pull the jammed paper out from any area where it is accessible. The paper may be pulled from either
fold table or exit conveyor
4. If the jam cannot be cleared using the above technique, the fold rollers will need to be removed as
described in section 4.1. Once the fold rollers are removed, clearing the jam is a simple matter of pulling
the paper from the rollers.

5.3 Feed Wheel Cleaning

As with the fold rollers, contamination of the feed wheel will result in poor performance. When feeding becomes
inconsistent, clean only the outer surface of the feed wheel with a clean dry cloth and alcohol or a mild soap and
water solution. Avoid getting cleaning solutions into the bearing surfaces. Do not use Martin Yale Roller Cleaner
and Rejuvenator or other solvent-based cleaner on the feed wheel, as damage to the rubber and bearing will
result. Never lubricate the feed wheel as it is permanently lubricated!
5.4 Bushings a Folding Rollers
After extended heavy use, the folding rollers and the bushing plates may become worn. In this case a replacement
cartridge is available.
