Following a cleared paper jam, now prints faded colors, faint bars and fair bit of black ink smudging at end of page.

try to stop the sheet just before it enters the fuser and see if the marks are on the paper already. if not then it has to be the fuser if they are them you have another issue.

Regarding your recent inquiry about your MX892 poor print quality/lack of printing performance (or similar), it sounds like your PRINTHEAD is either clogged (from dried ink) or has reached END-OF-LIFE, to help determine which please perform the following steps (if you have already performed a step, please continue to the next step in the order shown):



Canon Cartridge Troubleshooting: http://inkjet411.com/?page_id=1537





1.Go into the printer\'s maintenance/tools menu and print a print quality test (i.e. heading cleaning, nozzle test or similar) to help identify which color (of number of colors) is impacted.



NOTE: To help determine which color has run out, use the following suggestions in sequence until you are able to identify the empty color:



1) Generate a Print Quality Test Page from your printer control panel; a faded color band indicates empty. 2) To distinguish between a black and photo black cartridge, print a text document and/or a photo. Faded black in a text document indicates the black cartridge is empty; faded black in a photo indicates the photo black cartridge is empty. 3) To distinguish between cyan, yellow, and magenta click here: http://inkjet411.com/?page_id=146 A faded or missing color band indicates empty.



2.At the printer\'s control panel under the \'Maintenance\' or \'Tools\' menu, activate a \'CLEANING\' or \'HEAD CLEANING\' to prime the ink system. Then Run the Inkjet411 \'Ink Recovery Test Print\' from our Test Prints page to verify all colors are firing properly (all printers also provide some form of a Self Test page): http://inkjet411.com/?page_id=146



3.Check your user\'s manual to see if there are any procedures on cleaning the service station/capping station assembly (this is where the carriage/cartridges \'park\' when not in use). A dirty service station can cause all kinds of improper color output problems (assuming the printhead is working correctly of course). NOTE: May not be applicable for your model depending on the printer design.



4.If this does not remedy the problem, then one or more of the ink ports may be dry within the PRINTHEAD assembly (the ink cartridges physically connect to this electronic assembly). We suggest you either remove the printhead and perform a hot water flush for 2 minutes (in a sink) or using an eye-dropper, or similar, drip 5-10 milliliters (i.e. 1-2 teaspoons) of distilled water into the respective color ink port to help saturate the foam. http://inkjet411.com/?page_id=2804



7.Reinstall ink cartridges and retest.

8.If the problem persists, then you may have a damaged PRINTHEAD (worst case scenario), unrelated to the refilled cartridges. The printhead is a separate electronic assembly (which the cartridges are installed into) and is responsible for firing the ink drops onto the paper. Over time and based on usage this assembly will eventually fail (typically lasts ~4,000 to 5000 printed pages on avg). Refer to video on how the PRINTHEAD functions: http://inkjet411.com/?page_id=2054

PRINHEAD TECHNICAL NOTES:



IIT (individual ink tank-based) printer models have an electronic PRINTHEAD within the base of the carriage assembly (responsible for pulling ink from the 4, 5 or 6 ink cartridges and then firing the ink droplets onto the paper) - these will eventually fail depending on print usage type and printer duty cycle (i.e. rated for approximately 10,000 printed pages over life, but the consumer average is typically closer ~4,000-5,000 thruput pages). The printhead is replaceable and can be ordered directly from the manufacturer or www.Amazon.com . For information on how the PRINTHEAD functions, please watch the following video: http://inkjet411.com/?page_id=2054



Typically the printhead should not reach it\'s end-of-life until after a minimum of 8 or more complete sets of cartridge changes. While some printheads may last 10,000+ pages others may only last 2000 pages, actual results will vary. The printhead will eventually fail in time due to an internal micro-electronics failure, due to the following leading factors: general customer print usage and printer care, printer duty cycle (i.e. # pages printed per month), printing frequency (i.e. time between each print job), print mode (i.e. draft vs. normal) and content printed (i.e. photos vs plain pages) and color mode (black and white only vs. color/greyscale printing).



Paper types used (i.e. plain paper, photo papers & matte/heavy bond papers) and paper edge curl (i.e. duration in printer and/or exposure to low relative humidity) can also quickly lead to premature printhead failures due to physical \'head strikes\' of the paper edges making repeated contact with the printhead nozzle plate surfaces.

NOTE: If you need to purchase a new ink cartridge(s), we suggest you try a remanufactured ink cartridge from http://www.inkplicity.com/ as their ink cartridges typically have the lowest cost in the USA and have a high reliability rating.



-Thank you

Check for any small paper jam. Check the rollers, also use an alcohol swab to clean the rollers and check for ink leaking. Check you ink pad, it could be time for a new one.

Chances are high that the process of clearing the jam has resulted in ink being released from the cleaning/resting pad area based over on the right hand side (where the printhead sits when not in use).
This waste ink has probable come into contact with the rollers and other parts over on the right edge of the paper.
You'll probably see this ink slowly fade out and disappear over time. If it doesn't however there's something effectively feeding things so check the resting pad for a loose tube, overflow, puddles, etc...
If there's anything like that, report back (preferably with images).

How is the printer printing black and yellow color? Is it a smudge?

When I print, the pages are smudged with ink. What should I do?
Description: - If smudged stains appear at the top center of the printed page:

• Make sure the paper is not too thick or curled.
  Also, verify that the appropriate paper is being used and that the paper type set in the machine matches the media used.
• Make sure the paper is not curled when you print on the back side of the paper with the Print Odd Pages and Print Even Pages settings.

- If smudged stains appear at the right or left corner of the printed page:

• Make sure the paper is not curled when you print on the back side of the paper with the Print Odd Pages and Print Even Pages settings.

- If smudged stains appear on the reverse side or at the bottom of the page:
NOTE: Illustrations shown below are from the representative product and may differ from your Brother machine.

• Make sure the printer platen is not dirty with ink.

from cnet review of the product

• Unfortunately, as with the Z1420, fast print speeds come at the cost of print quality with the Z1300. Black text prints, though nicely dark, were beset by obvious jaggedness. The color graphics print had a slightly faded look to it and color blocks showed graininess and faint horizontal striations. Barcode-style patterns were muddled, too. For our tests, we printed color 4x6 photos with the standard black and tricolor cartridges, as Lexmark did not include photo ink tanks with the test unit. The colors were dull, details were hazy, and again, the entire print was marred by graininess and faint horizontal lines. That said, nobody buys a $25 printer to print photos for framing or to create displays for a classroom science project. A $25 printer is a convenience item for occasional reference prints, and as such, the Z1300 does its job.

What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

change ink cartdidge then try. check also paper jam.
if still problem then change ink cartridge then check.
