Oki c882 printer colours not vivid enough

SOURCE: Canon iP4500 colour management

Try this one:

In Photoshop, go to View>Proof Setup>Custom and select the ICC profile for the printer and paper that you will be using.
Canon iP4500 SG* is for printing with Canon Everyday Glossy Photo Paper (GP-501/401) on your printer.
Canon iP4500 SP1 is for printing with Canon Plus Glossy Photo Paper (PP-101) on your printer.
Canon iP4500 PR* is for printing with Canon Photo Paper Pro on your printer.
Canon iP4500 MP* is for printing with Canon Matte Photo Paper on your printer.
Select a rendering intent (i.e. Perceptual, Relative Colorimetric, Saturation, Absolute Colorimetric). I normally use either Perceptual or Relative Colorimetric on my Canon printers.
You might want to check black point compensation.
The display will now show you how the image is supposed to look once printed.
Edit the image based on the softproof.
Afterwards, go to Print With Preview.
Select the same color profile and rendering intent that you used for softproofing.
Choose Let Photoshop Determine the Colors.
Hit Print. Select the paper that you will be printing on. Go to Color Options. Select none for Color Correction.
Hit Print again.
Hope that helps.......

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 .

I bet that did not work. I had this problem on all three of my Okidata LED printers... right out of the box. And after replacing drums and toner. After tons of research I found that this is a side effect of LED technology.

The effect worsens when the stock is thick (cardstock) and coated (glossy finish).

Compared to a magicolor 7450 II the quality really is horrible.

SOURCE: does anyone know what is

If you look on top of the fuser roller(upper orange roller), there is a thermistor (orange rectangle plastic that rides on the roller) you will see four wires going into that housing. Two are for the thermistor and the other two is for the fuse that is built into the housing. You would have to use a soldering iron to melt the plastic that the fuse is sitting in. You would have to figure out what to use as a fast blow fuse.

Okidata makes it difficult to take out the thermistor because the nut is locktite on the screw. Try using the soldering iron to melt it. Just make sure you dont damage the thermistor.
