Available Paper

The permissible humidity range for paper storage is 25% to 75% (with a room temperature of 15°C to 27.5°C). Storing paper in a location that does not meet these specifications may affect the paper feed and image quality.

When you cut paper, the cutting sides of the paper must be made smooth using a polishing tool. To smooth the cutting sides of the paper, place it on a level surface, and move the polishing tool perpendicularly against the edges approximately three times. If you do not smooth all four sides of the paper, streaks may appear in images, or paper feeding may be adversely affected.

Depending on the type, ink used by offset printers may contain substances (such as solvents or wax) which cause it to soften or melt at high temperatures. The machine has a high toner fixing temperature, so using paper that has been printed with these types of ink may cause the ink to stick to the fixing unit, etc., causing output paper to appear dirty or the lifespan of parts to decrease. In order to prevent ink from melting, it is recommended that you use paper printed with heat-resistant oil-based (oxidation-polymerization-type) ink or UV-curable ink.

If the ink melts, the problem may be resolved by lowering the temperature of the fixing unit. However, this may cause a decrease in fixation. For more information, contact your local authorized Canon dealer.

Dry preprinted paper for a sufficient period (72 hours or longer) before use.

Do not print on portions where ink is already present, or portions which are varnished. Doing so may result in a dirty output with the toner not adhering to the inked surface (especially when coated paper is used) or an output with the moiré effect (a shimmering, wavy pattern), depending on the screen frequency and screen angles. If you must print on an inked surface, you may be able to improve the print result by printing on the area where the image density is very light. Also, for the moiré effect, you can improve the print result by adjusting the screen frequency. For more information, contact your local authorized Canon dealer.

Spray powders are particles that are applied to help prevent bleeding when printing using oil based ink. Feeding the paper with spray powders into the machine may cause the spray powders to scatter inside the machine resulting in dirty output or reducing the transfer performance of rollers and belts. Therefore, if you are using oil base inked paper, avoid using paper with heavy amounts of spray powders. If the problem continues to occur, we recommend you remove the spray powders. If the inside of the machine becomes dirty from the spray powders, contact your local authorized Canon dealer.

Do not use the paper that was printed with a full color laser printer. Since the toner adhering temperature for this machine is higher than the general color laser printer, if the toner of the pre-printed media melts, the paper may get jammed in the fixing unit and damage the machine. Also, even under the specified condition, the quality of the output prints may degrade due to reasons such as changes in the glossiness. If you must use a full color laser printed media, narrow the printing range and lighten the image density. However, if you are using a full color laser printed media, make sure you contact your local authorized Canon dealer.

You can use paper printed from a full color laser printer only if the paper is being used as the cover or sheet insertion by feeding it from the Document Insertion Unit-N, Document Insertion Unit-Q, or Document Insertion / Folding Unit-K. In this case, be careful of the paper curl and paper sticking together.

By feeding the preprinted paper into the machine, the quality of the paper may change. If the paper is still not fed correctly, perform <Adjust Paper Separation Fan Level>.

Wrap the preprinted paper in its original package, and store it in a dry place, away from direct sunlight.

When the Inner Booklet Trimmer-A is attached, avoid trimming the preprinted paper in high temperature and high humidity environment. The paper may be trimmed with uneven edges or the paper jam may occur.

Maintaining a curl amount of 5 mm or less for both upward and downward curling is recommended, regardless of paper weight.

For paper lighter than 105 g/m2, it is recommended that you maintain a curl amount of 10 mm or less for both upward and downward curling.

For paper from 106 g/m2 to 163 g/m2 in weight, it is recommended that you maintain a curl amount of 10 mm or less for upward curling and 5 mm or less for downward curling.

For paper from 164 g/m2 to 300 g/m2 in weight, it is recommended that you maintain a curl amount of 5 mm or less for upward curling. Using paper with downward curling is not recommended.

Paper that appears curled when viewed from the front of the feeding direction may cause gaps to appear between the side regulation plates inside the Paper Deck, thus causing the paper to be fed diagonally. If must use curled paper, ensure that the curling amount is kept at 5 mm or less.

For heavy paper (164 g/m2 to 300 g/m2), it is not recommended that you use curled sheets. Furthermore, using heavy paper (164 g/m2 to 300 g/m2) may still cause feeding problems, even if the paper is not curled. When using paper smaller than A4 size, it is recommended that you use paper with the paper grain parallel to the longer side. When using paper larger than B4 size, it is recommended that you use paper with the paper grain parallel to the shorter side.

For paper lighter than 105 g/m2, it is recommended that you maintain a curl amount of 10 mm or less for both upward and downward curling.

For paper from 106 g/m2 to 163 g/m2 in weight, it is recommended that you maintain a curl amount of 10 mm or less for upward curling and 5 mm or less for downward curling.

For paper from 164 g/m2 to 300 g/m2 in weight or postcards, it is not recommended that you use them if they are curled.

Store the paper on a flat surface.

Do not store paper together with items made from PVC (polyvinyl chloride), such as clear folders. The toner may melt, causing paper to become stuck to PVC-based material.

Store paper so that it does not become folded or wrinkled. Doing so may cause the toner to come off.

If you intend to store paper for long periods (two or more years), preserve them in a binder, etc.

Long-term storage may cause paper to discolor, which in turn may cause print to appear discolored.

Do not store paper in places with high temperatures.

Be sure to use insoluble adhesive.

Test the adhesive on an unneeded printout before using.

Before stacking printouts that stuck with adhesive, check that the adhesive completely dried.
