I have a HP 8100 printer, when i print a configuration page, the top half of the sheet prints very light(blurr), while the bottom half of the sheet prints good. At first i thought it was the toner, so i replaced it, the print job is still the same. So i ordered a maintenance kit and replaced the fuser roller etc.. It still prints the same. I tried restoring default factory setting and changed printing quality density, but still no luck. Any Ideas? J

Pl share printer model number for better solution.. try this# go to printer menu select default settings..check# check paper size in system..select proper size# un install existing drivers, re install once again..check# print from word or excel format..checkif no result share printer model number... for better solution...Vinay

It is either the toner cartridge or the fuser.
Put paper in the manual feed tray.
Print the Configuration Pages.
When the sheet is half way fed into the printer, open the top cover.
Remove the toner and look at the sheet of paper. If you see the black streak, the toner is bad.
If the sheet looks good, the fuser is bad. Probably a bad roller, which you can see looking at the fuser.

If this is a "ghost" image like whats on the top of the page is re-appearing on the middle and/or bottom. The fuser is defective and needs to be replaced. Part # RG5-4447

Issue with the duplexer... could be as simple as cleaning the rollers and things inside the duplexer.. or could be something major like replacing it.

Don't have a definitive answer.. sorry.

Hello sir; I suggest you go to replace a new cartridge, see what's happen.

Hello,

Here is the step by step right from the user manual. also here is a direct link to the manual.

Let me know how it works out for you.

Print on both sides of the page
You can print two-sided pages with the HP All-in-One manually. When printing two-sided
pages, make sure to use paper that is thick enough so that images do not show through
to the other side.
To print on both sides of the page
1. Load paper into the input tray.
2. On the File menu in your software application, click Print.
3. Make sure the product is the selected printer.
4. Click the button that opens the Properties dialog box.
Depending on your software application, this button might be called Properties,
Options, Printer Setup, Printer, or Preferences.
5. Click the Features tab.
6. In the Paper saving options area, select Manual from the Two-sided printing dropdown
list.

7. For binding, do one of the following:
• For binding on the top like a notebook or calendar, select the Flip Pages Up check
box.
This causes the odd and even pages of your document to print opposite of each
other top-to-bottom. This ensures that the top of the page is always at the top of
the sheet when you flip the pages up in your bound document.
• For binding on the side like a book or magazine, click to clear the Flip Pages
Up check box.
This causes the odd and even pages of your document to print opposite of each
other left-to-right. This ensures that the top of the page is always at the top of the
sheet when you turn the pages in your bound document.

8. Click OK, and then click Print or OK in the Print dialog box.
The product begins printing. Wait until all the odd-numbered pages are printed before
removing any of the printed pages from the output tray.
A dialog box displays instructions on the screen when it is time to process the second
side of your job.
9. Click Continue when done.

Hi Beadworker,

This information can be found by printing a configuration page from your printer. Follow these steps to print out a configuration page.

Printing a Configuration Page
You can print a configuration page from the printer’s control
panel. Use the configuration page to view the current settings,
to help troubleshoot problems, or to verify the installation of
optional accessories, such as memory or an optional tray.
To print a configuration page:
1 In ready mode, press the Menu button on the control
panel until you see “Information” on the bottom line of the
display.
2 Press the Enter button to access the menu.
3 Press the Enter button when “Configuration” displays
on the bottom line.
A configuration page prints out.
