Optional Cut Sheet Feeder
The cut sheet feeder makes
it easy to print on standard paper and letterhead stationery.
Paper handling is controlled automatically by the cut sheet
feeder, so you can print long documents without stopping to
insert a new page.
Paper Loading
- Set the paper set lever
of the cut sheet feeder to the RESET position.
- Slide the left paper
guide to the left end. (The paper guide can be moved by
loosening the paper guide fastening screw, and can be
fastened by tightening the screw.) With this paper guide
position, the first printing character is printed 0.5
inch inside the paper left end.
- Set the right paper
guide roughly to the paper right end.
- Riffle a batch of new
papers, place them between the left and right paper
guides, and push them slightly to the left and front.
- Adjust the right paper
guide position so that there is a gap of 1/64" to
1/32" between the guide and the paper right end, and
fasten the guide with the fastening screw.
- Set the paper set lever
to the SET position. Do not release and withdraw your
hand until the set lever is firmly engaged in the SET
position.
NOTE: Precautions for paper
installation:
- The cut sheet feeder
can hold a 5/8" stack of paper (about 200 sheets) at
one time. If paper is set exceeding 5/8", this may
cause paper jam or paper feed error.
- Only one-part paper can
be used; no multiple-part paper can be used.
- Do not use wrinkled,
folded or bent paper.
- Do not use paper of
differing sizes.
- Prior to setting a
batch of new papers, riffle them well so that the sheets
are separated from one another.
Paper Positioning
- Set the cut sheet
feeder in select state (SEL lamp lit) and press the
INSERT button to feed a sheet to the front of the platen.
- Position the paper at
the desired printing start line using the FWD FEED and
REV FEED buttons.
FWD FEED button moves the paper up 1/144th inch when you
press it. Hold the button down for continuous feeding.
REV FEED button moves the paper down 1/144th inch when
you press it. When the button is held down, the paper
moves in 1/3-inch increments. Be sure to allow at least a
1-inch margin at the top of the paper.
- Make sure the printer
is deselected (SEL light out) and press the TOF SET
button. This will set Top of Form at the current paper
position when the printer is selected.
Setting Form Length
You can set the from length
using either a software command or the FORM LENGTH dial on the
printer. If you use the FORM LENGTH dial, make sure the printer
is deselected (SEL lamp out), then set the dial for the desired
form length according to the table below. The form length will be
