Feeding Method Friction feed
Tractor feed (push: standard, pull : optional)
NOTES :
1. When using friction feed :
Adjust the paper release lever at rear position.
Use the paper tension unit.
Do not use continuous paper.
Do not use a single sheet paper shorter than 182 mm or longer than 257 mm
(LQ-860),
364 mm (LQ-106O).
Do not perform any reverse paper feed operations within the top 8.5 mm and bottom 22
mm area of the paper.
Do not perform reverse feed beyond than 1/6 “ after the paper end has been detected.
Do not use multi-part single sheet forms.
2. When using tractor feed:
. Multiple copies for printing must be finished by pasting them together at the line or dots.
. Copy paper must be a carbonless multi-part paper.
a) When using push tractor feed:
. Adjust the paper release lever at center position.
“ Use the paper tension unit.

“ Do not perform reverse feeding for more than 1/6 “.
“ Because accuracy of paper feed cannot be assured, do not perform reverse feeding
after the paper end has been detected.
b) When using pull tractor feed :
“ Adjust the paper release lever at front position.
“ Remove the paper tension unit and mount the pull tractor unit.
o Use the paper path when a single sheet is inserted.

Values in the parentheses apply to the LQ-106O.
Printing is possible for approximately 42 mm after the bottom edge of a page has been
detected. Thus, the value 13,5 mm (lowest print position) is given for reference only. Paper
feed accuracy cannot be assured in the area approximately 22 mm (0.87”) from the bottom
edge of the page.
