How to Identify and Fix Common Problems ?

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

The No Toner message appears if the toner cartridge or the toner cartridge and drum unit assembly is not installed correctly. Remove the toner cartridge and drum unit assembly. Remove the toner cartridge from the drum unit, and reinstall the toner cartridge back in the drum unit.
Toner Sensor

These sensors are covered with toner when the cartridge is full, then become exposed over time as you print pages and the toner level declines. When the cartridge reaches a level set by the manufacturer, your low-toner indicator will light.

“Toner Error” will appear on your machine`s display if one or more toner cartridges are not installed or not installed correctly.
Another reason for ink cartridge failure is that your cartridge chips or printer`s contacts might be dirty. It`s easy to fix your printer ink not working using a lint-free cloth and isopropyl alcohol. Take out the new cartridges from the printer and place it on a flat surface with a paper towel underneath.
The most common reason a refilled ink cartridge does not work is that you didn`t reinstall the cartridge properly. Check the cartridge and make sure it is not dislodged or misaligned. If there is no visible sign of misinstallation, remove the cartridge and reinstall it.
When “Toner Low” is displayed, prepare a new toner cartridge. If you do not have a new toner cartridge at hand and need printing before obtaining it, you can continue printing about 20 pages(*1) by opening and closing the front cover or the output tray. Print quality is not guaranteed.
Each printer uses an optical sensor in which shines a light through a prism at the bottom of the ink well. Once ink levels fall to a predetermined level, a beam of light bounces towards a low-ink sensor, which again triggers an on-screen message that tells you to replace the cartridge.
The most obvious sign of low toner cartridge is poor print quality. Streaking, lines or missed prints are all possible signs that cartridge replacement is imminent. If you have tried rocking the toner cartridge and are still getting poor prints, it is likely time to replace your cartridge.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
First, remove and reinstall the designated cartridge 2-3 times until it securely sits in the slot to overcome an HP printer cartridge error. Next, turn off the printer and take out all the cartridges. Gently wipe the cartridge and carriage contacts with a dry, lint-free cloth and reinstall again.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
Press the button on the chip-reset tool for several seconds until the LED light on the device goes off. Then, unlock the reset tool from the cartridge. Use the resetter with other cartridges and install them back into the corresponding slots in your printer. Voila!

Expired Toner and Suggestions for Source of Toner
ANSWER : Hi Frank, I had a very similar question two weeks ago, but my “old beloved workhorse” is an HP Laserjet 4L. From the good old days! I too had made bad investments in “new but old truly HP” toner cartridges, hoping to coax more life from my printer. I ended up choosing to try a remanufactured cartridge from www.4inkjets.com. It was a gamble, but the website said they had a 100% satisfaction guarantee. And I can tell you they have lighting fast service. I’ve now printed 50 pages without a flaw. JOY! While the cartridges and technology are different, I suggest you try the same place. And good luck!

Waste Toner Cartridge is empty but printer is still telling me to replace it
ANSWER : All of the ones I’ve seen are optical. Light shines through a transparent section of the waste box onto a photocell. If toner builds up past that area, it gives a warning to replace it. Possibly toner dust has gotten on the photocell.
