How do one correct print quality in hp color laser jet 2600n


Hi Good day!!
Follow this method hope it helps you!!

During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.
This printer has two processes for generating cleaning pages: one is automatically generated and one is manually generated. When a new black print cartridge is installed, a cleaning page will be automatically generated prior to calibration.
Clean the fuser using HP Toolbox
NOTE: Use the following procedure to clean the fuser using the HP Toolbox. To clean the engine when the computer is running an operating system that does not support HP Toolbox, see the late-breaking Readme on the root of the CD-ROM, or visit http://www.hp.com/support/clj2600n .


1 Make sure that the printer is turned on and in the Ready state.

2 Open the HP Toolbox using one of the following methods.
*
On the Windows desktop, double-click the HP Toolbox icon.
* On the Windows Start menu, click Programs (All Programs in Windows XP), click HP , click HP Color LaserJet 2600n, and then click HP Color LaserJet 2600n Toolbox .

3 Click the Troubleshooting tab, and then Troubleshooting Tools .
4 Click the Print button next to step 1, "Click the "Print" button to print out the Cleaning Page."

5 Remove the Cleaning Page from the output bin, and load it printed side down in Tray 1.

6 Click the Clean button to complete the cleaning process. Press the GO button on the printer control panel. The Cleaning page will print, with a second page adhered to the first page. This is normal behavior during the cleaning process.

Cleaning spilled toner
Defective print cartridges can develop leaks. Also, after a paper jam has occurred, some toner might remain on the rollers and guides inside the printer. The pages that print immediately after the jam can pick up this toner.
CAUTION: When cleaning the printer, do not touch the ETB with a damp cloth or with fingers.
Cleaning the paper path
The device features a special cleaning mode to clean the paper path.
NOTE: If there is access to HP Toolbox, HP recommends cleaning the paper path by using HP Toolbox.

2. Use the (LEFT ARROW) or the (RIGHT ARROW) button to select Cleaning Mode, and then press (SELECT).

3. Load plain letter or A4 paper when prompted.

4. Press (SELECT) again to confirm and begin the cleaning process.
A page feeds through the printer slowly. Discard the page when the process is completed.

NOTE: This will calibrate the color and clean the black electrostatic transfer belt (ETB).


1 Use the (LEFT ARROW) or the (RIGHT ARROW) button to select System setup and then press (SELECT).

2 Use the (LEFT ARROW) or the (RIGHT ARROW) button to select Print quality and then press (SELECT). Calibrate color will display on the control panel.

The Black prints faint on the left side of the page for our HP2605dn printer.


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.

HP Laser Jet 4700n-Light printing on right side of paper. Removed all cartridges and toner, cleaned and recalibrated after start up. Still light printing on right side. Any suggestions??


Is the light printing the same for black and white vs color? Light printing on a side is not uncommon for these printers. It is usually caused by the laser optics getting dirty. But this usually shows up more in one color than the other. Such as something printed in yellow is fine while red is faded on one side. If the light on the right side printing is the same on all colors including black then I would suspect something with your transfer unit.
If you do notice that it us just on black or another color then it is definately time to get the laser optics cleaned.

HP LaserJet 1500... prints color yellow ONLY


It's possible that the toner in the cartridge is not evenly distributed. You can redistribute toner if you gently shake the cartridge from side to side, then reinstall it to see if this affects performance. Please also see this article.
You might wish to use the guided troubleshooting option available from HP support here. Or have a look at the troubleshooting section in the user manual here. Then clean the engine & calibrate the printer, as described pg. 88.
If that's no help, please see this forum post and the linked attachments within.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

The folded paper solution for for me. Thanks to all for sharing!!!!

I had the same problem. No black or cyan on the left side of the pages. From this advice... I folded a stack of 4 pieces of paper in half and then half again. I took out the transfer unit and put the folded paper in the upper left corner and then put the transfer unit back in. WORKS BEAUTIFULLY! Thanks you all sooooo... much!

Colors faded on left side of paper black and blue


Is it possible for you to clean the printheads manually with cotton buds and cleaning solution on this unit. Clean all thoroughly and this might just correct issue.
