Just the paper for placing all size improves the use range of printer, by the graduation mark in pressure roller shaft during traversing
Spacing size can be accurately adjusted, improves operating efficiency, pressure holding can be carried out to paper by tabletting in use, protected
Paper is demonstrate,proved and alice phenomena impair printing effect occurs in course of conveying.
The present invention is compact-sized, easy to use, it is possible to achieve multi-angle, multi-faceted transport operation, convenient use, to pass through
Moving sliding sleeve adjustment positioning set between spacing, enable locating ring fix with paper both ends, can not only avoid being subjected to displacement,
So as to improve print quality, and the paper that can place all size improves the use range of printer, and paper can
Rational to meet a variety of use demands of Paper Printing using paper is economized on, device entirety using flexible, operating efficiency is high,
With higher practicality, there is good economic benefit and social benefit, suitably promote the use of.
