I am getting Error 40..turn off and turn on error again and again from HP 2605 Color laser jet printer. Plz help.

49 errors are most commonly caused when the printer receives a print job with commands it does not recognize. You can try updating the firmware as this will often resolve the error. Go to HP's website to find the most recent firmware, however this model is fairly old and likely the firmware update will be fairly old.

You can find the driver for HP Color LaserJet 2605 Printer series by visiting this website:

Then choose the operating system of your computer.
Goodluck!

Your printer "consumes":

1. paper
2. ink (either liquid-ink in an "ink-jet" printer, or dry toner-ink in a "laser" printer)

Refresh the supply of these "consumable" items.

It's a firmware error.
Do ALL your print jobs give this error. If it is just one job that causes the error, something is corrupted with the software.
If every print job causes the error, it's the printer. Try printing after removing DIMMs from the printer. If you can try plugging the printer into another port on the computer or router.
When all else fails, go to www.hp.com/#support and download the latest firmware and install it.
By all means READ the directions first.

Faded prints are possible due to following reasons.

1. Fogged red mirrors inside the Laser box
2. Alignment of the Laser Box
3. Calibration Problem
4. Cleaning Problem

I will guide you with simple steps first, if this dosen't work working with laser box is little tough & time consuming, hence will describe later.

To Calibrate the colors, Press the 'Green Button' in the front panel, use the arrow keys to navigate through menu.

Select 'System Setting' by pressing the green button again, navigate using the arrow keys and select the 'Calibrate Color', select green button to select and confirm to 'Calibrate Now'. This will take few minutes.

In addition to that, to clean the paper path, select the green button and use the arrow keys and navigate thru' menu and select 'Service'. select using the green button and navigate through menu and select cleaning option. This will take few minutes.

Try printing some documents and check whether you have fixed. If you have not got the original print quality, Let know to guide you more technically.

Sounds like a faulty sensor. Buy a can of compressed air blow it throughout the printer. Sometimes toner dust sits on the sensors giving a false reading. If after this you still get an error you're going to need a printer engineer!

The problem is usually caused by printing a PDF file with fonts/page size/ page formating errors which will cause the printer to display the 49.3048 error. The only way to use the printer is to POR or recycle the power and delete the print job from the server or spooling device and cancel it on the printer before the offending command is issued to the printer again. You can try updating the firmware to the latest version 46.140.5 from the HP website. MIke L.

Use the bundled disc to install the drivers. If you do not have Vista drivers with it, you can download them from the hp site

plz try with another cartridge
