My HP 5200 printer prints very light as if its cartridge is low while its toner is full, this problem was present from the very first day i purchased it, changed toner cartridge but no effect, (meaning no problem with toner cart.), what could be the possible reason ???

Toner cartridge memory counts how many print outs passing through it, once memory sensed yield count crossed, printer will say that "low toner" , after couple of prints it will says to "replace the cartridge". If you refilled this cartridge with out replacing the memory printer will treats its old cartridge only.. Replacing the memory will solves your problem.
Ideal memory chip...

TONER OUT
The toner cartridge has run out of toner.
Depending on how the printer has been configured, it will either continue to print or stop.
Due to the resolution of the toner level sensor, it is possible that a small amount of toner (less than one percent) might still be present in the cartridge.
1. If the printer has stopped, you can resume printing by pressing GO for each job.
2. Replace the toner cartridge.

1. Power cycle the printer and Verify the "Replace Cartridge?? message is still present.
2. Remove ALL the cartridges (Toner and Drum cartridges).
3. Power cycle the printer
4. Install one by one of the cartridges when the printer requests them
5. Verify that the new cartridge is recognized by printing the Supplies Status Page.

Memory Supply Error 10.00.00 The printer is unable to read or write to the print

cartridge e-label, or the e-label is not on the cartridge.

Basically what is happening is the printer cannot read the small chip on the toner cartridge. The chip is located on the toner cartridge as it is inserted into the printer. 1 - Make sure the toner is firmly seated into the printer. 2 - Power cycle the printer with the toner out of the printer. Install the toner back into the printer. 3 - Install another toner cartridge. 3 - Verify that the e-label connector is firmly seated in connector

In this case, actually it is not the Black toner that got depleted. Here the message being displayed indicate that one of the color Toner supply need to be replaced as it got depleted and currently the printer is printing in Black and white using the Black toner cartridge.

in this case, to troubleshoot these issues please try performing the following and check for the results.

* 1. Check for the level of the toner cartridges:

a) Check from the HP Toolbox application. Here are the steps to be performed from your PC:

* Access the Toolbox software.
* Select the Status tab.
* Select the Device status option.

Here you can check for the supplies status in terms of the % remaining for each toner cartridges.

b) By checking the supplies status from the printer control panel display.

On the printer display when printer is in Ready mode the supplies status can be checked from the supplies level indicator. Each toner cartridge and the Imaging drum level will be indicated by a bar which varies according to the level of the supplies present.

c) Print the supplies status page from the printer.

* On the printer control panel menu, press Menu .
* Use the (Right Arrow) button to select Reports, and then press Enter .
* Use the (Right Arrow) button to select Supplies Status, and then press Enter .

If any of the color toner cartridges and the Imaging drum have a low supply level replace them with genuine HP print cartridges.

The part numbers of the consumables are as follows:

* Black print cartridge - Q3960A
* Cyan print cartridge - Q3971A
* Magenta print cartridge - Q3973A
* Yellow print cartridge - Q3972A
* Imaging Drum - Q3964A

Great you changed the toner cartridges but you may also need to do the following as well.

Imaging drum is low Light pattern Description The imaging-drum light is on. The printer continues to print without any action required until the imaging drum is empty. Action Order a new imaging drum. Have a good day

There is a toner sensor in this printer that shoots a beam of light through the toner cartridge. As long as the toner is full and blocks the light, it sees it as being full. If it were the sensor, it would tell you this for all the toners, though. The printer also calculates how much toner may have been used and gives warnings based on that. It could be that this isn't getting reset after you change toner. You can reset the toner gage by going into the reset menu and selecting "New xxxx cartridge" and changing it to YES.

The symbol on top that looks like a beaker full of marbles is the symbol for the toner cartridge (notice the same symbol is found on the button that opens the toner cartridge door). If this light is on, either the toner cartridge is getting low, or the cartridge needs replaced.

It means that the printer is in READY State.

Control panel
The printer control panel is comprised of six lights and two buttons. The lights produce patterns that
identify the printer status.
1 Jam light: Indicates that there is a jam in the printer.
2 Toner light: When the print cartridge is low, the Toner light illuminates. When the print cartridge is out of the printer,
the Toner light blinks.
3 Paper out light: Indicates that the printer is out of paper.
4 Attention light: Indicates that the print-cartridge door is open or other errors exist.
5 Ready light: Indicates that the printer is ready to print.
6 Go button and light: Initiates action or indicates status.
7 Cancel button: To cancel the print job that is currently printing, press the Cancel button.

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
light blinks). The lights also indicate when a non-HP print cartridge is installed (the light
blinks and the Attention light is on).
