Introduction > 13

When the rear paper stacker is folded down paper exits the printer through the rear of the

printer and is stacked here face up. This is mainly used for heavy print media. When used

in conjunction with the multi purpose feed tray, the paper path through the printer is

essentially straight. This avoids bending the paper around curves in the paper path and

enables feeding of up to 250g/m² media.

APER

RECOMMENDATIONS

Your printer will handle a variety of print media, including a range of paper weights and

sizes, labels and envelopes. This section provides general advice on choice of media, and

explains how to use each type.

The best performance will be obtained when using standard 75~90g/m² paper designed

for use in copiers and laser printers. Suitable types are:

> M-Real Data Copy Everyday 80g/m²

> Color Copy by Mondi 90g/m²

Use of heavily embossed or very rough textured paper is not recommended.

Pre-printed stationery

Envelopes

Labels

Recommended type is Avery White Label types 7162, 7664, 7666 (A4), or 5161 (Letter).

CAUTION!

Pre-printed stationery can be used, but the ink must not offset

when exposed to the high fuser temperatures used in the printing

process.

Continued use of pre-printed stationery may cause the paper feed

performance to degrade over time and paper jams may occur.

Clean the paper feed rollers as described on page 64.

CAUTION!

Envelopes should be free from twist, curl or other deformations.

They should also be of the rectangular flap type, with glue that

remains intact when subjected to hot roll pressure fusing used in

this type of printer. Window envelopes are not suitable.

CAUTION!

Labels should also be of the type recommended for use in copiers

and laser printers, in which the base carrier page is entirely

covered by labels. Other types of label stock may damage the

printer due to the labels peeling off during the printing process.

ASSETTE

TRAYS

If you have identical paper stock loaded in another tray (2nd or 3rd tray if you have one,

or multi purpose tray) you can set the printer to automatically switch to the other tray when

the current tray runs out of paper. When printing from Windows applications, this function

is enabled in the driver settings. When printing from other systems, this function is enabled

in the Print Menu. (See “Menu functions” on page 23.)

ULTI

PURPOSE

TRAY

The multi purpose tray can handle the same sizes as the cassette trays but in weights up

to 250

g/m². For very heavy paper stock use the face up (rear) paper stacker. This ensures

that the paper path through the printer is almost straight.

The multi purpose tray can feed paper widths from 76mm to 215.9mm and lengths from

127.0mm to 1320mm (banner printing).

For paper lengths exceeding 356mm (Legal 14in.) use paper stock between 90g/m² and

128g/m² and the face up (rear) paper stacker.

Use the multi purpose tray for printing on envelopes. Up to 10 envelopes can be loaded at

one time, subject to a maximum stacking depth of 10mm.

The rear output tray at the rear of the printer should be opened and the tray extension

pulled out when required for use. In this condition paper will exit via this path, regardless

of driver settings.

The rear output tray can hold up to 100 sheets of 80g/m² standard paper, and can handle

stocks up to 250

g/m².

Always use this stacker and the multi purpose feeder for paper stocks heavier than

188g/m².

OADING

PAPER

ASSETTE

TRAYS

1. Remove the paper tray from the printer.

Fan the paper to be loaded at the edges (1) and in the middle (2) to ensure that all

sheets are properly separated, then tap the edges of the stack on a flat surface to

make it flush again (3).

NOTE

For illustrative purposes, the C712 printer has been shown. If you have a C612

printer, the principle is the same with any exceptions noted.

Loading paper > 19

3. Load paper (letter headed paper face down and top edge towards the front of the

printer), as shown.

> Adjust the rear stopper (a) and paper guides (b) to the size of paper being used.

To prevent paper jams:

> Do not leave space between the paper and the guides and rear stopper.

> Do not overfill the paper tray. Capacity depends on the type of paper stock.

> Do not load damaged paper.

> Do not load paper of different sizes or types at the same time.

> Close the paper tray gently.

CAUTION!

C712 ONLY: IMPORTANT: Set paper size dial (c) to the size of paper

being used (A4 in the above example).

Loading paper > 20

> Do not pull the paper tray out during printing (except as described below for the

2nd tray).

NOTE

> If you have two trays and you are printing from the 1st (upper) tray, you

can pull out the 2nd (lower) tray during printing to reload it. However, if

you are printing from the 2nd (lower) tray, do not pull out the 1st (upper)

tray. This will cause a paper jam.

> For face down printing, make sure the rear output tray (a) is closed (the

paper exits from the top of the printer). Stacking capacity is

approximately 250 sheets for the C612 and 350 sheets for the C712,

depending on paper weight.

> For face up printing, make sure the rear output tray (a) is open and the

paper support (b) is extended. Paper is stacked in reverse order and tray

capacity is approximately 100 sheets, depending on paper weight.

> Always use the rear output tray for heavy paper (card stock, etc.).

CAUTION!

Do not open or close the rear paper exit while printing as it may

result in a paper jam.
