Question about OKI C3400n Laser Printer

1 Answer

Poor quality print

I have a OKI 3200 and the black print quality is becoming faint down the left side of a black printed page.
Colour appears okay.
The status monitor indicates all is in order, the drum was replaced recently and to be sure I replaced the black cartridge today and it has not improved the quality.

Try cleaning the LED heads. These are located in the lid and are facing you when you have raised the lid. A quick wipe with a dry cloth or tissue should help. If in doubt, check the user manual.

Dymo LabelWriter 450 Twin Turbo - Until recently worked fine from both sides. Suddenly, no longer printing from left - prints half a label, then stops, then error message says Out of Paper, the blue light...


See if it still happens using a fresh label roll. From the Dymo 450 User Guide the common causes of poor print quality issues.

Poor print quality is most frequently caused by one of the following:
• An old roll of labels
• Labels made by a manufacturer other than DYMO
• Labels where the thermal coating has been compromised
• A dirty print head
First, make sure you are using DYMO-branded labels. Do not use third-party labels because the thermal coating on other labels has a different sensitivity than DYMO-branded labels. Also, the perforated holes between the labels made by other manufacturers are frequently not detectable by LabelWriter printers.
If the print quality becomes faint, small dots of white appear scattered through the printed characters, or light and dark patches of printing appear, you are probably using a faulty roll of labels. Try using a different roll from a fresh box. If the second roll prints correctly, the problem is with the first roll of labels.
Another possibility is that the LabelWriter print head needs cleaning. Every LabelWriter printer comes with a cleaning card. See "Caring for Your Printer" on page 17 for information about the
LabelWriter cleaning card.

Replaced black ink cartridge, but now it only prints a very faint line, cant make out what is printing


Sir/Madam

If your printed pages have a horizontal line in the text or graphics (as shown in the illustration below) or blank text, some of the nozzles may be clogged and need to be cleaned

Go to Section 2 for instructions on how to print the Alignment Check sheet and adjust the print alignment.

Section 1: Checking the print quality and cleaning the print head

  1. Print a Print Quality Check Sheet.

    1. Press Menu.
    2. Press the UP OR DOWN ARROW key or the dial pad to choose Ink Management and press OK.
    3. Press the UP OR DOWN ARROW key or the dial pad to choose Test Print and press OK.
    4. Press the UP OR DOWN ARROW key or the dial pad to choose Print Quality/Alignment and pressOK.
    5. Press Color (Colour) Start. The machine begins printing the Print Quality Check Sheet.
  2. Closely examine the Print Quality Check Sheet. Each of the four colors is represented by a slanted square pattern made up of individual blocks. The colors should appear in the following order from left to right: Black - Yellow - Cyan - Magenta.
  3. Compare the print quality of the Check Sheet you just printed with the three examples listed below:

    (A) One or more complete blocks of colors are missing:

3539a464-0a65-438d-8089-d017bae2e5c6.gif


(B) Most of the short diagonal lines are missing from one or more color blocks:

  2. The display will then ask you if the print quality is OK for Color. Press the DOWN ARROW key or 2 to chooseNo for color with the problem.
  3. The display will then show Start Cleaning? Yes No.
    Press the UP ARROW key or 1 to choose Yes and the machine will start cleaning the color ink cartridges.
  4. When the machine completes cleaning the print head, press Color (Colour) Start. Another Print Quality Check Sheet will print.
  5. Repeat the cleaning and the quality check process following the Step 4-7.
  6. Compare the second or third Print Quality Check Sheet with the first one you printed in step1:
9. Compare the second or third Print Quality Check Sheet with the first one you printed in step1:

  • If the print quality on the first Check Sheet matched Example (A) or (B) and you do not see any improvement on the second or third Check Sheet, please contact Brother Customer Service from "Contact Us."

  • If the print quality on the first Check Sheet matched Example (A) or (B) and you see some improvement on the second or third Check Sheet but it's not perfect, repeat the cleaning and the quality check process three more times (totally five times). If you do not see any further improvement after that, please contact Brother Customer Service from "Contact Us."

  • If the print quality on the first Check Sheet matched Example (C) and you do not see any improvement on the second or third Check Sheet, repeat the cleaning and the quality check process three more times (totally five times).

  5. Press Black (Mono) Start or Color (Colour) Start. The machine begins printing the Alignment Check Sheet.
  6. By reviewing this Check Sheet, you can determine if the alignment needs adjustment.
  7. Examine the 600 dpi and 1200 dpi test prints on the Alignment Check Sheet. If the number 5 sample of both the 600 dpi and 1200 dpi most closely matches the 0 sample, press the UP ARROW key or 1 to choose Yes.
    If one of the other samples is a better match for the 0 sample, press the DOWN ARROW key to choose No. The display will then prompt you to choose the sample that most closely matches the 0 sample for 600 dpi and then 1200 dpi.
  8. Press Stop/Exit.
If the print quality continues to be poor, go to Section 1 to clean the print head.

The print is faint. The lettering on the excel spreadsheet is Arial Regular 10, colour - automatic and normal font. However, the printed copy appears grey rather than black. Toner cartridge recently...


normally you go to printer settings and look for where it says page quality. make sure the page quality is set to normal or fine. this will make it black. if it is on a setting lower than this it will cause the printed document to appear grey.

cheers.

On Canon iRC 3200 Laser Printer:: streaks of fainted print


if one side prints well its not the fuser,plus those fusers normaly make alot of noise when they start to act up. right above the bypass tray is a cover with a screw in the front of it. remove this and inside is the ITB belt(two blue handles) if you pull it out there is a metal plate on the bottom bending this up can solve this problem. the paper can drag across this plate causing streaks.hope this helps.

Faint area down left side of page


When you say "Cleaned the lens" I presume you mean the four LED print heads. Use a spirit to clean them with if the toner dust is hard to remove. I usually just use a finger and wipe the entire length. Make sure there is no foreign item laying on the drum top where the black plastic film is as the led head may not seat properly on it. Clean all the silver high voltage springs down the left side of the printer. They make contact with the drums. If you still have a problem then try printing solid colour blocks ie Yellow, Magenta ,Cyan and Black . This will identify which colour is giving the problem . Change that drum and all should be well.

Oki C3100 - v poor print quality


Hi Errol

The way to identifiy your problem is to send a full colour print to your printer and open the top just as the paper starts to come out . if you then remove your toner / drums for all the colours you can see the transfer belt if the quality of the image that you can see on the transfer belt is good and clear your problem is with the transfer form the tranferbelt to the paper and not any toner /drum issue and the most likley cause is the transfer belt itself "but before you relpace it remove it and clean around the electrical contact points and generally make sure the internals of the printer is free of loose toner .

Pring quality on Samsung CLP-300 colour laser


If you the image is faded and your toner supply is good, the problem is the developer blades in the imaging unit. During the normal use of the printer, there is a buildup of toner that sticks on the developer blade. The developer blade meters the amount of toner that gets to the drum that ultimately makes it to the paper. As the toner buildup increases on the blade, less and less toner that gets to the drum cause the image to fade.

To fix this problem you will need to disassemble the imaging unit and clean the blades or buy a new imaging unit. I have clean my blades and I don't have 20000 images it is about 7000 and I have a document to show you if you are handy.

I'm not an expert on these but I'd guess either the high voltage unit or LED laser PSU are suffering from an intermittent problem. If you're lucky it's just a loose connector - but I'll bet you've already tried re-seating every connector you can find :)
