Control-panel lights (HP LaserJet 1010 series printers)The printer indicates status and errors through patterns of the GO, READY, and ATTENTION lights. If anylights are blinking, the error can usually be resolved.1If the error pattern occurs when printing, try pressing the GO button to continue.2Make sure that the print cartridge is installed correctly and the print-cartridge door is closed.3Turn the printer power off and then on again.Control-panel light patterns (HP LJ 1010 series printers)The lights on the printer, from back to front, are the GO, READY, and ATTENTION lights. Each light can beon solid or blinking. When the three blink in sequence, the activity is called “cycling.” In this document,the light status is represented as follows:OnBlinkingOffCyclingFigure 6-1 Control-panel-lights legendTable 6-4 Control-panel light patterns (HP LJ 1010 series printers)Printer onDuring Initialization/startup, the lightscycle one after another in a front-to-backpattern (the "landing lights" pattern).Pressing buttons has no effect when thisis the printer status.AttentionReconfig initializationGoReadyWhen a power-on function is activated(for example, during a cold reset orNVRAM initialization) the lights cycle asin the startup state.

JamsClearing jamsCAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove jams.Damage caused by sharp objects will not be covered by the warranty.CAUTION Always pull jammed media in the direction it would travel through the paper path.Do not pull jammed media against the direction of travel through the paper path to avoid damageto the printer.To prevent damage to the printer when clearing jams, including jams in the output bin, always open theprint-cartridge door and remove the print cartridge. Keep the door open and the cartridge out until thejam has been cleared. Opening the print-cartridge door and removing the print cartridge relieves tensionon the printer rollers, which prevents damage to the printer and makes the removal of jammed pageseasier.Occasionally, media becomes jammed during a print job. You are notified of a media jam by an errorfrom the software and the printer control panel lights. See Control-panel lights (HP LaserJet 1010 seriesprinters) on page 102 or Control-panel lights (HP LaserJet 1020 printer) on page 106.The following are some of the causes of media jams:ŶThe input trays are loaded improperly or are too full. See Loading media on page 25.NOTE When you add new media, always remove all of the media from the input tray andstraighten the stack of new media. This helps prevent multiple sheets of media from feedingthrough the printer at one time, reducing media jams.ŶThe media does not meet HP specifications. See Media specifications on page 21.Typical media jam locationsŶPrint cartridge area: See Removing a jammed page on page 43.ŶInput tray area: If the page is still sticking out of the input tray, gently try to remove it from the inputtray without tearing the page. If you feel resistance, see Removing a jammed page on page 43.ŶOutput path: If the page is sticking out of the output bin, see Removing a jammed pageon page 43.NOTE There might be loose toner in the printer after a media jam. This toner clears up aftera few sheets are printed.Removing a jammed pageUse the procedures in this section to remove a jam.CAUTION Media jams might result in loose toner on the page. If you get any toner on yourclothes, wash them in cold water. Hot water will permanently set the toner into the fabric.www.partshere.comPartshere Troubleshooting
CAUTION To prevent damage to the printer when clearing jams, including jams in the outputbin, always open the print cartridge door and remove the print cartridge.To prevent damage to the print cartridge, minimize its exposure to direct light. Cover the printcartridge with a sheet of paper.NOTE The following illustrations show the HP LaserJet 1020 printer. The same procedure isused to remove a jam in the HP LaserJet 1010 series printers.1Open the print cartridge door, and remove the print cartridge.2Grasp the middle edge of the side of the media that is most visible, and carefully pull it free fromthe printer.CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to removejams. Damage caused by sharp objects will not be covered by the warranty.CAUTION Always pull jammed media in the direction it would travel through the paper path.Do not forcefully pull jammed media against the direction of travel through the paper path toavoid damage to the printer.www.partshere.comPartshere Troubleshooting
3When you have removed the jammed media, replace the print cartridge, and close the print cartridgedoor.After clearing a media jam, you might need to turn the printer off then on again.NOTE When you add new media, remove all of the media from the input tray and straightenthe stack of new media.www.partshere.comPartshere Troubleshooting
