Question about Konica Minolta bizhub Office Equipment & Supplies

1 Answer

I have a Bizhub C280 that prints color copies with vague, horizontal yellow lines going across the bottom and works its way upwards.I have replaced the developing unit. Black and white copies r fine.

The problem went away for about a business week 5 days but then came back with the same issue that I began with. I've also cleaned the PH unit, as well as, the transfer belt, behind the transfer belt, and each drum individually.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

SOURCE: Horizontal colored lines through grayscale printed photos

Hi George,

It sound's like an ink-feed issue:

1) Dirty heads, even after cleaning
2) No-ink or poor quality ink
3) Damaged head: some are part of the cartridge, some are not
4) Air bubbles in ink

The test page is typically not as hi-res nor as saturated as a
photo print. The hi-res photo puts the greatest demand on the print head.

The color lines you see are actually lines of missing color,
where the head has failed to deposit ink, so one or two primary
colors are missing from the complete picture.

For example missing yellow will make a blue line.
Missing magenta will make a green line
Missing cyan will make a red line.... etc..

Clean the heads again and again, print again and again,
hoping to flush the system.

BUT, keep in mind that cleaning wastes huge amounts of
ink and tiny little cartridges of ink cost more than many new printers.

SOURCE: BLACK LINE ACROSS THE COPY CANON IMAGE 2200

Most likely your drum unit is worn out. If it reaches the yield of 50k or more, it starts to develop grooves in the drum and toner gets stuck in the groove and is applied to your pages. If you have a service company, they can change it for you. We sell the drum for $220.

SOURCE: Dell 5100cn - Magenta color on all prints

Hi 56tbird.

The answer you got from Dell was partially correct.

It is the Magenta Developer that is causing your problem, however, you can replace this part for less then the printer if you do the work yourself.

I have successfully instructed other on replacing the developer units, although you will have to procure the part.

This is one of the 4 color assemblies you see when you remove the imaging drum.

The part number for the Magenta Developer is M6090

The first thing to do is price the part. I usually suggest doing a google search for the part number. you will find many resellers that way.

you might also try a search on Ebay for the part number as well.

If you decide to purchase the part, if you somewhat mechanically inclined, you should be able to replace the part without a problem.

I can give you detailed instructions on how to change the developer if you decide to go that route.

Thanks,

Cory

You didn't mention the size of the job size, but it sounds like a memory problem. If you have a service contract or it's still under warranty, contact your rep before you start opening things up.

The following is if you don't have a service contract. If the bizhub has been working with no problems in the past, try reseating or replacing the RAM. I've had to replace RAM that started causing problems on classroom computers. If you bought it refurbished (used) check to see the 2GB RAM that supposed to come with the bizhub hasn't been removed or replaced with smaller memory.

Lexmark z705 printing blank envelopes soft ware ok


The problem that you are experiencing is caused by the way the text is formatted in most word processing documents. By default envelopes are printed not in black, but a dark gray. This confuses the printer and causes it to use the color cartridge to process gray instead of using the black cartridge.

You can fix this problem with one of two ways:

1. Click on "Start", "Control Panel" and click on "Printers and Faxes." Right click on the "Lexmark Printer" icon and select "Properties." Click on "Printing Preferences." Go to "Quality/Copies" tab and select the option "Print color images in black and white."
2. You can also change the color of you text to a true black in your word processor. This will require you to resort to the word processor's documentation and help files.

Both of these settings will cause your printer to use the black cartridge instead of the color. If either one of these solutions solves your problem, it means your color cartridge needs to be cleaned or replaced. If you feel that the color cartridge should not be out of ink, please follow the steps given below:

Clean Nozzle Procedure:

1. Go to the "Solution Center" and click on the "Maintenance" tab.
2. Select "Clean to fix horizontal strips."
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.

If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzles" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:

“Wicking” Procedure:

1. Select "Install color/black cartridge" and remove the cartridge from the printer.
2. Get a damp paper towel.
3. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
4. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
5. Next dab the cartridge on the towel to make sure that the ink is flowing.
6. Snap the cartridge back into the printer.
7. On your computer, select "Old Cartridge installed."
8. Repeat the "Clean to fix horizontal strips" procedure listed above.

If this procedure does not help, please let us know so that we can continue with technical support.

Color cartridge do not want to print


A technique to improve print quality is to try and clean the cartridge nozzles. You may clean the cartridge by following the steps given below:
1. Go to the "Lexmark solution center." This can be done by clicking on "Start," go to "Programs" and Lexmark printer group. Click on the "Lexmark Solution center." Next click on the "Maintenance" Tab.
2. Select "Clean and Fix Horizontal streaks." Click on "Print". This will produce a printed page.
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.
If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzle" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:
1. Please open the "Solution center" again and go to the "Maintenance" Tab.
2. Select "Install color/black cartridge" and remove the cartridge or cartridges from the printer.
3. Get a damp paper towel.
4. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
5. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
6. Next dab the cartridge on the towel to make sure that the ink is flowing.
7. Snap the cartridges back into the printer.
8. On your computer, select "Old Cartridge install."
9. Repeat the "Clean Nozzle Page" one more time. If this fails to address the problem the entire procedure may need repeating.
