How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
Turn on the printer

Connect the power cord between the printer and a grounded AC outlet. Move the power switch on the lower-right bottom of the printer into the On position, and then press and release the On/off button on the front of the printer.

Common factors include driver problems, software issues, hardware failures and overuse.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.
If it does not turn on, reset the power module. With the power cord connected to the printer and a working wall outlet, turn on the printer. If the printer turns on, wait 2 hours, disconnect the power cable, and try using the printer with battery power only.
In Windows, search for and open Add a printer or scanner . Click Add a printer or scanner, and then wait for Windows to locate available printers. If your printer is found, click it, and then click Add device to complete the driver installation.
Print blemishes after inserting a new cartridge. Slow print times. Abnormal noises. Paper jams and ripped paper.
You must press the power button to turn the printer back on.
Printer sleep mode

Check that the printer does not have sleep mode enabled: Go to Control Panel > Devices and Printers. Right-click the printer in question, then select Printer Preferences. Look for an option to disable sleep or time-out mode.

Battery Troubles:

If your HP laptop has a removable battery, remove it and reinsert it after a few seconds. Sometimes, a faulty connection can cause the power light to blink. If you can access a spare battery, try swapping it to see if the issue persists.

Turn the printer off then back on. If the issue persists, turn the printer off, unplug the power cord and then wait at least three minutes before plugging the power cord back in and turning the printer back on. If the issue persists, ensure the product is running the latest firmware available from HP.com.
The Power button is blinking. This condition might be caused by an open ink cartridge access door, an empty input tray, a paper jam, or a carriage jam. An error message might display on your computer. If a `paper jam` error message displays on your computer, try the steps to clear the paper jam.
The average lifespan of a printer is around 3-5 years. With proper upkeep and maintenance, some printers can last longer, but eventually your machine will need an upgrade.
Printers used to print a few documents a week likely only need annual servicing, whereas an office printer that is in constant demand likely needs servicing more frequently. With proper care and maintenance, your office printer can last several years.
Sometimes called a forced reset, this allows you to clear the memory if Windows or other software are unresponsive or if there are problems with the display or the computer. Performing a Hard or Forced Reset on Your HP Notebook (Fixed Battery)
Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on. Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.
The reset key is a single use key and once used cannot be used again. All EPSON printers have inbuilt counters that count up the number of pages a printer produces, the number of head cleans executed and various other attributes. Once a critical level is reached the printer will enter its service mode.
First set up your grandparents with a Wi-Fi network, then connect an HP wireless printer to that network. (No computer needed. The printer connects right to the Wi-Fi network.)
Use of HP Smart is NOT mandatory. You may use different Scan applications and software to scan and save / print / share your data.
Turn on the wifi connection on your mobile or laptop. Then find the printer`s wifi direct name and connect it. Most printers have a password on the back or in the settings. Now you can use that printer without any wifi connection or the internet.
Working out how much you use your current printer is a good way to determine the benefit of repairing it. Printers have a lifetime volume limit. If you are still a long way from hitting that limit then printer repair makes good sense. But if you are nearing the limit, the cost of repairing it might not be worth it.
As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.
As much as you may love your HP printer, you don`t want to spend more than it is worth repairing it! As a general rule, if your HP printer cost less than $200 new (and you don`t have a surplus of ink or toner cartridges), you may be better off looking at replacement options.

Lexmark paper feed problems
ANSWER : On my X204n Lexmark laser printer, it was doing the same thing you described – basically sounded like it was trying to pick up the paper from the tray and then failing after several seconds. When you’d open the paper tray, the paper looked like it had been partially taken up with some black scuff marks on the paper that lined up with the rollers that take up the paper. I inspected the rollers and although they looked a bit smooth and worn, didn’t seem like they should be a problem. However, this particular model has just a rubber tire almost like a car tire – the rubber can come off the hard plastic wheel on the inner portion. So I popped off the two rubber “tires”, turned them inside out and put them back on. When turned inside out, the rubber looked nice and … rubbery and had a lot more grippy feeling to them. The very first printing attempt after that and the paper sucked up perfectly with no problems. I think the problem is solved! So if you have similar “tires” that take up the paper, try flipping them and see if it works for you too.

P4015 P4515 Noise Problems
ANSWER : I have a 4015 that has optional tray3, and optional tray4-1500 sheet stacker. The noise goes away if I remove the optional trays, and run printer by itself. When I add back either tray the noise comes back. from what I have read the tray1 electromagnetic clutch assembly drives the optional trays when they are installed. Is this clutch assembly available to replace or is it part of the whole tray 1 pick up assembly? This noise is not related to fuser or toner. Very frustrated customer and tech.
