HP 2550 will not print. Green light flashes. I'm asking it to print a page that is 159kb and I suspect it is too low on memory. Why is that? My son's Hp 2550N won't print either.

If the machine is making "working noises" while it flashes, it is most likely calibrating. A good way to find out if the problem is due to connectivity issues with your computer is to turn the machine off, unplug for 1 minute, plug back in and turn on. Wait until the light is solid, indicating its ready to go, and then press and hold the green button until the lights flash. It should produce a demo print for you. If it doesnt, the problem may be with the printer, not the computer. Also, check in the "Printers and Faxes" settings in the control panel (if you are running windows) to see that the 2550 is set as the default printer.

HP recommends to use genuine HP cartridges else it will damage the cartridge mechanism. Replace the samsung cartridge with genuine cartridge and check for the result.

How to print a configuration page from an HP LaserJet P1102w


freginold_0.jpg

The HP LaserJet Professional P1102w is a compact wireless desktop printer. It is very easy to set up and use. Unlike larger HP printers, the P1102w does not even have a true operation panel; it only has a power button, a cancel button, and a wireless button.

However, like just about every other HP printer, the P1102w has the ability to print out a configuration page that displays many of the printer's settings and statistics. This page is called the self test / device configuration page, and on it you can find the printer's page count, number of paper jams (broken down by section), amount of available memory, network settings, and more.

To print the device configuration page, make sure the printer is on and ready. The green light on the top left side of the printer should be lit. If the red light is lit or flashing, then there is a problem with the printer -- such as no toner or a paper jam -- and you won't be able to print the configuration page until the problem is rectified. You'll also need to have at least one sheet of paper loaded into the paper tray. Make sure the two side fences and the rear fence are snug against the paper to prevent misfeeding.

Press and hold the cancel button (the button with the red X on it) for about four seconds. The printer will warm up and begin making noise, and the green light will start to flash -- when these two things happen, you can release the cancel button. The printer will print out the configuration page, face down, and once it has finished the green light will stop flashing and the printer will quiet down.

How to use all of the Toner in your HP 2550 series printer


Most laser printers on the market today use a computer chip to tell the printer/computer when it's empty. The chip does not have any kind of physical sensor to tell whether the toner is actually low or not, instead it keeps track of how many pages were printed using the toner cartridge. (there is a separate chip on each cartridge, so in a color printer there are 4 chips one of each color and one on the black)

The chips tell your printer/computer that they are low or empty long before the toner is actually low or empty. If you replace them when the computer tells you to you are throwing away a lot of good toner.

To make things worse, the printers will not print at all (color or b/w) once it believes that one of the cartridges is empty.

There are 2 ways to 'trick' your printer into not believing that a cartridge is empty.

(Solution 1)
The chips that are on the cartridges can be swapped out with new ones. There are several vendors that sell aftermarket chips for your 2550 toner cartridges. Do a general search for 2550 reset chip and you will find vendors that sell reset chips. You can also find them on eBay for around $20-$25 a set.

The chips themselves are very simple to replace. Use a small screwdriver and pry off the old chip. They are just held in place with a strong piece of double sided tape. If the old tape is still there and good, you can just put the new chip in it's place, otherwise stick the new one on with some double sided tape.

This trick can also be used to extend the life of your printer drum, as you can buy reset chips for it as well.

(Solution 2) A bit clunky, but this one is free
You can literally trick your printer into not reading the info from the chip and thus not stopping you from printing. This solution is not as nice and clean as the first one, but it does work and it's free. You will have to repeat this solution from time to time if the printer stops working.
  • Step 1: Power off your HP2550 printer.
  • Step 2: While the printer is off, press and hold the big green button on the printer.
  • Step 3: While still pressing the green button, power the printer back on using the power button (lower back corner on the left side of the printer).
  • Step 4: Continue to hold the green button while the printer initializes. During this time all of the front lights will turn on one at a time and then all but the first green light (the ready light) will turn off one at a time - this step can take several minutes to be patient and keep holding the green button.
  • Step 5: When all the lights have turned off except the front green light, release the big green button. The front lights with flash a few time, while they are flashing, press and release the red circle button 1 time.
  • Step 6: You may have to reload the printer driver at this point. If your computer has detected new hardware then go ahead and reinstall the driver.
Be aware
  • Some of the back cartridge lights (the back 4) may stay on or flash, this is OK.
  • The front green 'Ready' light will no longer be on, again this is OK.
  • If at any time your printer stops printing all together, then go through these steps again. I have had to redo this about 10 times over the past 2 1/2 years. It is a nuisance, but it saves a great deal of money.
  • If this does not work the first time then try it again. Each step must be done in order and correctly otherwise it does not work.
I have had my printer for almost 3 years now. The original cartridges that came with my printer stopped working because they told the printer they were empty about 2 1/2 years ago. I started doing this at that time and all 4 of mine (I have a 2550 color printer) are all still working and have not started to fade, so there was a lot of toner left when my printer said it was empty.

Green horseshoe light is continually lit


If it is solid on, it means the printer is ready to print; no action is required. If it's flashing, it means the printer is processing data and should print soon.

If you are printing from your computer and nothing comes out, with the "Horseshoe" light staying solid, I suggest checking the connection between your computer and the printer, or at least the printer configuration. Most of the time, unplugging, then plugging cables back in does the trick.

Color toners are empty


Press Green Tick, Right, -> System Setup -> Right, Right, -> Print Quality, Right -> Replace Supplies. Change from stop at out, to override at out. It'll let you print, and you'll get loads more out of your toner before the pages start to fade.

Flashing Lights


From the User Guide:

Black, Cyan, Magenta, and Yellow Supplies Status lights
These lights indicate when a print cartridge is low (the light is on), or empty or missing (the

blinks and the Attention light is on).
