Dell 1600N MF Laser Printer- Blank vertical strip on all prints

Does this happen if you make a copy? Or print any internal form meter count sheet demo page etc.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

Try printing a test page. Is it also blank? If so, you should check your ink system (cartridges full, etc.)

This is usually cause when you have more pages on your document which are blank. Check your document before printing in the preview section.

Replace the DRUM

The following table should help

Contamination in the laser path - 1. Clean the laser path. (Remove the laser/scanner assembly and clean the lens.) 2. Replace the laser/scanner assembly

Defective fuser - Replace the fuser assembly.

Lack of toner or faulty toner cartridge - Redistribute the toner in the toner cartridge. If the problem continues, replace the toner cartridge.

Dirty Corona Wire - Clean the Corona Wire.

Defective Drum - Mostly applies to B&W printers. Clean the drum or replace the drum.

If the print rubs off the page, this means the toner is not being fused to the page. Fused......this is done by the fuser. This would have nothing to do with light print.

The dell (1600n and 1815n /1815dn) printer drivers has a toner saver mode, which can contribute to light print.

To turn Toner Save Mode off, (Windows XP) perform the following steps:

1. Click the Start button, click Settings, and then click Printer and Faxes.
   The Printers and Faxes window appears.
2. Right-click Dell Laser MFP 1600n, 1815dn, and left-click Printing Preferences.
   The Dell Laser MFP 1600n, 1815dn Printing Preferences window appears.
3. Click the Advanced button.
   The Dell Laser MFP 1600n, 1815dn Advanced Options window appears.
4. Click to highlight Toner Save.
5. Click the drop-down list and change it to Off and click OK.
6. Click OK.

One thing that you mentioned in your post "it takes the printer forever to warm up". The fuser does have to reach operational temperature in order for it to fuse the toner to the page. So it is possible that you are having fuser problems, because of the time it is taking for it to warm up. Another thing that can contribute to the warm up time is not plugging the laser printer directly into a wall outlet. This would be true for any laser printer, not just a Dell laser printer. The low voltage power supply is what works the fuser, along with sensors and other motors in the printer.

Replacing the fuser and or the low voltage power supply in this model of printer is not an easy task. If using a Dell branded toner cartridge and checking the toner saver mode does not fix the issue. Then you would be looking at more expense then the machine would possibly be worth.

If it makes verticle lines only when using the document feeder it is most likely a dirty glass strip over the scanner light bar. If it makes verticle lines in all modes (printing, flat bed scanning/copying, receiving faxes) it could be the fuser or a dirty glass over the laser where ever the laser images to a drum roller (usually a larger green roller). It is possible that this green drum roller is inside the toner - if so - replacing the toner cartridge could fix it. Maybe you could try an old used toner to see of the problem changes - if so - it is very likely that a new toner would fix your print quality issue.

Clean the small glass strip on the left side of the scanner. There is probably some dirt there and will only show up when using the ADF.

Looks like mark on drum.. Change the toner cartrige .. If the printer is older, could be that the exit rollers are worn out..

Any difference between using the document feeder and just the flat bed?
