Printing problems When the printer is turned on the cartridges slam back and forth and then still will not print. The light blinks on and off on the printer.

Open the printer cover and access the cartridge area. Remove the cartridges. Check the transparent strip(encoder strip) and make sure it's not unseated from its position. If it is, - Switch off the printer. - Slide the cartridge carrier to the middle of the printer by taking the top part of the belt and moving it gently to the right. - Place an index finger on the encoder strip on either side of the cartridge carrier. The encoder strip is a clear strip running the length of the printer, above or behind the cartridge carrier. - On the back of the cartridge carrier, there is a small slot that the encoder strip fits into. Slightly push the encoder strip down and then back up to get it into the slot. - Then lightly press the strip first to the rear and then forward, if necessary.
Try to print again.

Clean encoder strip, thin plastic strip runs width of machine pararell to silver scan rail. Ensure it is running threw carriage smoothly otherwise the light that read it is dodgy, this will be unecomical to fix unless dirty strip

Introduction The printer lights indicate the printer status. These lights can be on, off, or blinking (flashing), depending on the status of the printer. The sections below describe the most common combinations of blinking lights, how to fix the issue, and how the issue is caused. NOTE: The light patterns included in this document are described as blinking or flashing lights. For the purpose of this document, "flashing" means the same as "blinking." Blinking lights Printer lights can can blink for more than one reason, so the solution can vary. These solutions need not be performed in a specific order, but solutions for the most common issues are presented first.

I have a Dell 924 and the SAME thing is happening to me! it is probably because something called the cartridge band has disconnected. it is actually a thin small clear band that connects to either side of the inside of the printer to guide the cartridge. Unfortunatly, if you don't still have a warrenty with Dell to get it fixed or replaced, you might have to buy a new one or fix it yourself. :(

Buttons and lights on the printer Two buttons and three lights are located on the front of an HP Deskjet printer.

• The lights tell when the printer is working or when it needs attention.
• The buttons help control the printer.

Buttons and lights Purpose POWER button and light Push the POWER button to turn the printer off and on. When lit, the light shows that the printer is turned on. RESUME button and light The light blinks when there is a problem with paper. When the problem is corrected, press the button.

Troubleshooting blinking printer lights Blinking lights Reason

All lights are off. The printer is off (asleep).

Press the POWER button to turn the printer on.

The printer should turn on automatically when a print job is sent to it.

The POWER (top) light is on. The printer is idle.

The printer is ready to print a document.

The POWER (top) light is blinking. The printer is busy printing.

Allow enough time to print. When a document has many fonts or graphics or uses complex color such as a color photo, it takes longer to begin printing.

The PRINT CARTRIDGE (bottom) light is blinking. Possible causes:

• The front cover is open. Make sure the front cover is completely closed.
• The print cartridge is missing. Make sure the print cartridge has been installed correctly.
• The print cartridge is broken or incompatible. Lift the front cover, and wait for the print-cartridge cradle to slide out. Check the part numbers on the print cartridge:

Black: 51645A

Color: C1823D,

If the print cartridges are compatible and correctly installed, they may be defective. Try replacing the print cartridges.

If none of the above suggestions fix the problem, and, if the error message still occurs, it may be a hardware failure. Call the HP Customer Support Center.
