Canon NP6050 Service Manual

I. FEATURES

1. The NP6050 is capable of making as many as 50 copies (A4, horizontal) every minute. With the RDF in stream reading mode, further, it can turn out as many as 60 copies every minute (A4, horizontal; onecopy-per-original).

2. It uses newly designed pick-up and feedrng mechanisms so that It not only helps save space, but it also is less susceptible to jams.

3. It provides high durability and high image qualrty required of high-speed copying. The use of the Canon-unique A-Si (amorphous silicon) photosensitive drum ensures high durability while the single-component toner projectron mechanism promises high-quality images for a long time.

4. It is equipped with a large-size liquid crystal display, offering easy-to-understand instructions.

in relation to the selected original and copy sizes.

Note, however, that the RDF will convert any

non-default original size into a default size so that auto ratio selection will be executed with reference to default sizes.

- Note:

You cannot select auto reproduction ratio in

combination with auto paper selection.

In page composition mode, two or four originals will be reduced and copied on one sheet of paper.

This mode may be any of the following four

types:
