Change the advanced media settings

[Low temperature mode]

• Pre-printed: The system is able to handle pre-printed media without problems if the guidelines regarding pre-printed media and inks are taken into account. Contact your local Canon representative to get a copy of these guidelines. In case media or inks are used that are not listed in the guidelines, the use of pre-printed media can lead to undesired print quality issues. To postpone print quality issues arising, a [Low temperature mode] is available on the printer. It is advised to enable the [Low temperature mode] when there are problems with processing pre-printed media. The interval between undesired print quality issues will then be increased significantly (for some temperature sensitive inks, but no guarantee for all inks).

  It is advised to enable the [Low temperature mode] when you process pre-printed media.

  It takes several minutes until [Low temperature mode] is reached.

  The [Low temperature mode] should not be enabled when you use media heavier than 120 g/m². This could lead to print problems.

• A secondary benefit (to pre-printed support) is to save energy. The preheater operates on a lower temperature.

[Double-sheet detection]

Double-sheet detection warns you if two or more sheets have been separated from the media stack in a paper tray at the same time. However, it is not always convenient to have the double-sheet detection enabled, for example when you use transparent media with a cover sheet. Then you can set the [Double-sheet detection] to [Off]. By factory default, [Double-sheet detection] is [On].

[Enhanced media mode]

Glossy media can cause a collating or stapling error in the finisher. You can set the [Enhanced media mode] to [On] to prevent the error. This will decrease the productivity of the printer. By factory default, the [Enhanced media mode] is [Off]. When you set the [Enhanced media mode] to [On] and the printer status is [Printing...], the dashboard displays a message that the enhanced media mode is enabled.

The [Enhanced media mode] is only available on printers that are equipped with an optional finisher (see The output locations).

[Paper quality]

Good media is best run with the highest paper quality setting: [Normal].

Lower grade media with respect to paper dust, such as some book papers for example, can leave more paper dust in the printer. This can lead to ghost images on prints directly after the black image cleaning procedure or to ghost images of previous pages on prints. When you use lower grade media, you can improve the print quality, with respect to these undesired ghost images, by changing the value of the [Paper quality] setting to [Low] or even [Lower]. However, this affects the productivity by almost 5 and 10% respectively.

Please refer to the Troubleshooting chapter for more information (see Troubleshooting).

[Paper quality test]

This test helps you to check if the correct [Paper quality] setting is set. In the Settings Editor, you can select the media for this test. It is advised to choose the same media as used for the job. Or, in other cases, choose media which covers the width of the media used as a minimum. When you start the [Paper quality test], the printer sends 5 empty sheets of the selected media to the system output. This is done after each of the next 5 black image cleaning procedures. Keep in mind that this can last 2500, 1250 and 1000 sheets when the [Paper quality] setting is set to [Normal], [Low] and [Lower] respectively. Then the test stops and the print job continues without interruption.

Check the last set (fifth) of the empty sheets to see if the [Paper quality] setting is cleaning the print process properly. The sheets should show no pollution.

NOTE

When the system goes into standby mode before the [Paper quality test] has finished, the [Paper quality test] starts again.
