Feeding Method

NOTES :

1. When using friction feed :

2. When using tractor feed:

Friction feed Tractor feed (push: standard, pull : optional)

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 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.

. 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.

(LQ-860),

1-3

REV.-A

“

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.

WV I

1~1 I

c) ‘A’’---

Adjust the paper release lever at front position. Remove the paper tension unit and mount the pull tractor unit. Do not loosen the paper between the platen and the pull sprocket. Precisely the horizontal position of the pull sprocket and push tractor. Do not perform reverse feeding for more than 1/6”. Do not perform reverse feeding after the paper end has been detected.
