FAX-L1000 Chapter 3: Technical Reference
2.2 Mechanical Overview
The mechanical section of this fax comprises the scanner section, the pickup section, and the
printer section.
2.2.1 Unit layout diagrams
a) Scanner section
The scanner section has an ADF (auto document feeder) function and can automatically
feed 50 sheets of A4 or letter size documents (20 sheets of B4 (AE only) or legal size
documents). This section has a stopper mechanism to hold documents properly. A contact
sensor scans one document in about 1.4 seconds (standard).
b) Pickup section
The pickup section feeds recording paper from a multi-purpose tray or front cassette to the
printer section. The universal type multi-purpose tray can hold up to 100 pages at a time, or
paper to a maximum height of 0.39" (10 mm), whichever is the lesser, and the guide
positions can be adjusted for letter, A4, and legal paper sizes. The front cassette can hold up
to 500 pages at a time, or paper to a maximum height of 2.20" (56 mm). The recording
paper is fed into the printer unit one page at a time, powered by the main motor.
c) Printer section
The printer section uses a new LASER beam printer engine.
It uses the surf fixing system that activates the heater only when printing to save power and
shorten the wait time.
2.2.2 Document and recording paper flow
a) Document flow
When the document is inserted into the document insertion slot at the main unit, it is fed by
the pick-up roller to the separation roller , and one page at a time is separated. Then, the
document is fed onto the contact sensor unit by the feed roller, and ejected by the eject
roller to the document output tray from the document outlet at the front of the main unit.
b) Recording paper flow
When recording paper is fed from the paper cassette, one sheet of paper is separated from
the others and transferred by the pickup roller and separation rollers. When it is fed from
the multi-purpose tray, one sheet of paper is separated from the others and transferred by
the pickup roller and separation pad. It is then inverted by the feed roller and at the same
time fed from the pickup section to the printer section. Then, after the recording paper is
printed by the printer section, toner cartridge and fixing section, the paper is ejected by the
face-down delivery roller and the paper feed roller at the recording paper outlet on the main
unit.
