If the Printer Makes a Strange SoundIf the Printer Makes a Strange SoundCause Corrective ActionThe printermakes a soundduring opera-tion.The following sounds do not indicate a problem with the printer.• There is a sound of suction from the PlatenTo 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 sideWhen 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 printingThere may be a fluttering sound when large paper is advanced.• If you suddenly hear the tone for cleaning operationsAt regular intervals, for printer maintenance, cleaning operations will begin automatically, even if the printer isin Sleep mode.• If you suddenly hear the tone for ink agitationAt regular intervals, to ensure optimal printing quality, the ink is agitated automatically, even if the printer is inSleep mode.The ink is also agitated automatically under the following conditions.

This consumes a lot of ink. This doesnot indicate a problem with the printer.Head Cleaning B in the ControlPanel menu is executed fre-quently.Head Cleaning B in the Control Panel menu consumes a lot of ink. This does not indicate aproblem with the printer. Unless the printer has been moved or stored for a long period or youare troubleshooting Printhead problems, we recommend not performing Head Cleaning B, tothe extent possible.You have just finished initial in-stallation, when more ink is con-sumed to fill the system.After initial installation or at the first-time use after transfer, ink flows into the system between theInk Tank and Printhead.Although the amount of remaining ink may drop as a result, it does not indicate a problem.The Printhead nozzles are clog-ged.Check for nozzle clogging.(See "Checking for Nozzle Clogging.") ➔ P.585Ink Level DetectionInk Level DetectionInk level detection will be deactivated if you load ink tanks once emptied.Ink level detectionInk tanks specified for this printer feature an ink level detection function to prevent the ink from running out duringprinting, which prevents printer damage. (See "Ink Tanks.") ➔P.574This function will not work correctly if you use refill ink tanks. As a result, printing stops. Thus, before using refill inktanks, you must cancel the ink level detection.Printing with the ink level detection canceled may lead to printer damage and printing problems. Canon Inc. is notliable for any damage that may occur as a result of refilling ink.iPF850 If the Printer Makes a Strange SoundUser's GuideTroubleshooting Other problems647
