If the Printer Makes a Strange Sound iPF785 If the Printer Makes a Strange Sound Cause The printer makes a sound during operation. Corrective Action The following sounds do not indicate a problem with the printer. • There is a sound of suction from the Platen To prevent paper from rising, paper is held against the Platen by suction from Vacuum holes under it. • There is a sound when a different size of paper is used and when the Carriage goes from side to side When paper of a different size is used, a valve is automatically activated to switch the area for paper suction, which may make a sound. This mechanism prevents suction from Vacuum holes where there is no paper. In addition, ink is ejected in sync with the movement of the Carriage back and forth to ensure optimal ink flow. At this time, the valve automatically switches the area for paper suction, which may make a sound. • Roll paper makes a fluttering sound during printing There may be a fluttering sound when large paper is advanced. • If you suddenly hear the tone for cleaning operations At regular intervals, for printer maintenance, cleaning operations will begin automatically, even if the printer is in Sleep mode. • If you suddenly hear the tone for ink agitation At regular intervals, to ensure optimal printing quality, the ink is agitated automatically, even if the printer is in Sleep mode. The ink is also agitated automatically under the following conditions. Note that other operations are not possible while "Agitating..." is displayed on the control panel. • After the printer is turned on In other cases, contact your Canon dealer. Troubleshooting Messages advising to check the maintenance cartridge are not cleared Cause The printer has not detected the new Maintenance Cartridge that was used to replace the old one. Corrective Action Remove the new Maintenance Cartridge you have just installed and insert it again firmly. (See "Replacing the Maintenance Cartridge.") ➔P.606 Other problems The printer consumes a lot of ink Cause Many full-page color images are printed. Head Cleaning B in the Control Panel menu is executed frequently. You have just finished initial installation, when more ink is consumed to fill the system. The Printhead nozzles are clogged. Corrective Action In print jobs such as photos, images are filled with color. This consumes a lot of ink. This does not indicate a problem with the printer. Head Cleaning B in the Control Panel menu consumes a lot of ink. This does not indicate a problem with the printer. Unless the printer has been moved or stored for a long period or you are troubleshooting Printhead problems, we recommend not performing Head Cleaning B, to the extent possible. After initial installation or at the first-time use after transfer, ink flows into the system between the Ink Tank and Printhead. Although the amount of remaining ink may drop as a result, it does not indicate a problem. Check for nozzle clogging. (See "Checking for Nozzle Clogging.") ➔P.597 Ink Level Detection Ink level detection will be deactivated if you load ink tanks once emptied. 652 Ink level detection Ink tanks specified for this printer feature an ink level detection function to prevent the ink from running out during printing, which prevents printer damage.
