I have a HP Deskjet D4160 printer, printer is not working anymore, i have an arrow blinking all the time on the left side, have tried disconnecting and reconnecting plus unable to find problem in trouble shooting guide, can u help?

The following page documents all blinking light errors: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00635074&tmp_task=solveCategory&lc=en&dlc=en&cc=us&product=501857&lang=en . Which cables did you remove when you " tried disconnecting and reconnecting"? Was the printer on when you removed the cable.

I assume you mean the light with the rectangle with a bent corner and the arrow pointing towards the user on it. This is the Resume button/light. If none of the other lights are blinking and the power light is on, check if there is an error message on the computer. This error message will display if you have the full software driver package installed. See the section for blinking resume light for pictures and all of the steps. (I'll summarize them below.)

If you do not have the software installed, check the following.
1) Is the printer out of paper or unable to pick up the paper? (If you have the error message "Out of Paper" this section applies.) Add more paper then press the Resume button. Remove the paper from the tray and check for any torn bits of paper or foreign objects in the tray. Check that the rollers are also clear of foreign objects. (Clear the rollers if needed). Place a stack of paper that is between 10-25 sheets (uniform size, unwrinkled) in the paper tray and press Resume. See if that clears the problem.

To clean the rollers, use a lint free cloth and bottled or distilled water. Turn off the printer and unplug all of the cables. Remove the rear access door, use a slightly dampened cloth (squeeze out the excess water). Then place the cloth against a roller and rotate the roller upwards with your fingers. Apply a moderate amount of pressure Repeat this for all of the rollers then allow the printer to dry (10-15 minutes). Finally replace the access door and plug in the printer. Press Power to turn on the printer.

2) A paper jam (This will be the error given on the computer) Turn the printer off and on after a 60 second wait. Print a test page (press and hold the Power button then press the Photosmart Express button). Release both buttons. The test page should print; if it doesn't, follow the rest of the directions. Clear any paper jams from the unit (be carefull not to tear any paper). Turn off and unplug the printer. Then remove the rear access cover and remove any paper from there. Next lift the printer cover and remove any paper from that area. Use a flashlight to check the corners. Slide the cartridge carrier and check under it. Make sure the cartridge carrier moves freely. Move the cartridge carrier to the left if it is on the right. If it is on the left or in the middle, move it to the right. Check both directions. Close the top cover and replace the rear access cover. Then plug in and turn on the printer. Attempt to print a self-test. Stop if the error is gone and the self-test prints. Otherwise, clean the rollers (see above). If the issue persists, reset the printer. Turn on the printer then remove the power cord from the printer. Then unplug the cord from the wall. Wait at least 15 seconds before replacing the power cord in the outlet and then the printer. Turn on the printer (if needed and try a self-test). If the error persists, the printer needs service. Contact HP if the printer is still under warranty.

3) Cartridge error. Make sure the appropriate cartridges are properly seated in the correct slots in the carrier. Remove them and reseat them. Clean them (damp Q-tip and bottled water) - clean the electrical contacts only. Let dry and then replace the cartridges (make sure they are fully seated). Try new cartridges then do an alignment of the cartridges (from the computer - use the Printer Toolbox). Try resetting the printer as in issue 2. Again the printer needs service if the error persists.

Note: plug the printer into the wall outlet directly during the reset. I like to remove the usb cable from the printer and the computer during resets. Sometimes waiting 5 minutes is better than 15 seconds. For the software, see http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&lc=en&dlc=en&product=501857 . Select your OS and click Next.

I hope this helps.

(if the printer is out of warranty, you need to decide if it is worth the cost of fixing.)
