4 Operation
(Continuance)
4.2 Feed Adjustments
If the edges of the folded paper do not line
up, adjust the skew by turning the Skew
Adjustment Knob slightly. Retest with a few
sheets and adjust as necessary to square
up the fold.
If hesitation occurs when automatically
feeding paper, double check the position of
the Paper Guides as described in section
2.5 of this manual. However, if hesitation
continues, the problem could be the type of
paper you are folding, or that the Retarder
is adjusted too tight.
If you are attempting to fold coated or gloss
stock, it may be necessary to increase the
pressure of the paper stack against the
Feed Wheel. The Feed Table lift-spring
tension is factory set to give the best overall
performance. However, this spring tension
is user adjustable. The Feed Table pressure
adjustment lever is located on the inside
frame of the 1711, below the Feed Table
and above the Second Fold table (See
Figure 3). Raising the adjustment lever will
increase the feeding force.
4.3 Manual Feed Operation
The Model 1711 is capable of folding single
sheets or sets of sheets up to 5 pages of
#20 Bond manually (one set at a time). To
do so, set up the machine as described
earlier in section 2. With the Feed Table
empty of paper, insert the paper all the way
into the Multi Sheet Bypass until the paper
stops. Press the Pulse Key (See button E
of Figure 8) and hold until the folded paper
exits the conveyor.

4.4 Folding Stapled Multiple Sets
The Model 1711 is capable of manually
folding stapled sets of paper, up to 5 sheets
of #20 Bond, in the same manner as
described in section 4.3.
Warning: To prevent jams or roller damage,
always attach the staple parallel to the fold
rollers, always feed the paper stapled edge
first, and avoid using loose fitting staples or
inserting them too close to the edge (less
than 5/16", 8mm).

5 Maintenance

5.1 Fold Roller Cleaning
During normal operation, the fold rollers will
become contaminated with paper dust, ink,
copy toner and other performance inhibiting
materials. At some point this will cause
problems such as wrinkling or marking the
paper and even miss-folds or paper jams.
At which time, cleaning the rollers will be
necessary. Follow these steps to gain
access to the rollers:
1. Disconnect the power cord from the
outlet
2. Remove both Fold Tables
3. Remove 2 Phillips screws from the Top
Cover, and remove the Top Cover.
Clean the exposed rollers by spraying
Martin Yale Roller Cleaner and Rejuvenator
onto a clean cloth and wiping until all
contaminates are removed. While wiping
the rollers, rotate the rollers to insure that
the entire surface of the roller is cleaned.
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.

5.2 Clearing Paper Jams
Use the following steps to clear a paper
jam:
1. Disconnect power to the folder
2. Remove the First and Second Fold
Tables
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
If the jam cannot be cleared using the above
steps, perform the following:
1. With a large flat bladed screwdriver,
insert and engage the rollers through
the Dejamming Port located in the Front
Cover.
2. While pulling on any exposed paper,
rotate the screwdriver in either direction
to clear the paper jam.
5.3 Feed Wheel Cleaning
As with the Fold Rollers, contamination
of the Feed Wheel will result in poor
performance. When
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 will result.
5.4 Oiling
The Model 1711 has 10 oil impregnated,
bronze bearings; 2 for each of the four
rubber fold rollers, and 2 for the feed shaft.
Generally, these bronze bearings DO NOT
require oiling, except in cases of extreme
use.
If needed, apply a single drop of light
machine oil to each end of the above
mentioned shafts, where the bronze bearing
and shaft meet. DO NOT over oil the bronze
bearings as the oil will eventually transfer to
your paper.
To gain access to all 10 bronze bearings,
remove both Fold Tables and the Top Cover
per the steps in section 5.2 - Clearing Paper
Jams.
