Re: How to fix toshiba photo copy machine not printing...
If your Toshiba photocopier is not printing in black and white but is printing in color, there are a few possible causes and solutions to try. Here are a few things you can try:
Make sure the machine is set to print in black and white. Some photocopiers have a setting that allows you to choose between color and black and white printing. Check the settings on your machine to make sure it is set to print in black and white.
Check the toner cartridges. If the black toner cartridge is full but the machine is still not printing in black and white, there may be a problem with the cartridge. Try removing the cartridge and shaking it gently to redistribute the toner inside. Then, clean the contacts on the cartridge and the machine to ensure they are making good contact.
Check the fuser unit. The fuser unit is responsible for heating and fusing the toner onto the paper. If the fuser unit is not working properly, it can cause the machine to not print in black and white. Check the fuser unit for any damage or debris, and clean it if necessary.
Check for any error messages. If your machine is displaying any error messages, try to troubleshoot the problem based on the specific error message. You may be able to find the meaning of the error message and a solution in the user manual for your machine.
If none of these solutions work, you may need to contact Toshiba for technical support or service. They may be able to help you diagnose and fix the problem with your machine.

Check whether you are running as Black and White or Gray Scale. Many printers only print straight black by using all four toner cartridges- Cyan, Magenta, Yellow, black. If are running colored print in black and white and u choose grey scale it will automatically give you a screened image as a light print.
Your CYAN is one of 3 colors the "Smart guys" came up with to make 252 some colors. Between Cyan Magenta Yellow and the ever so present Black you can make all your colors. Obviously you don't need the three C,M,Y to make a black and white copy. So the issue remains that a low or empty Cyan (pronounced S-eye-ann)
A couple differant issues I've run into since the creation of color copies near 2003 is A pull tab on the toner isn't pulled off before inserting the tube. Another is for several possible reasons the toner just isn't getting down into the developer mixing auger. There is also, upon occasion a situation that the motor that turns the toner auger inside the new toner cartridge doesn't turn enough/properly/ or at all. These days that will almost always throw a code in the display window. My 23years of Toshiba tells me try your C cartridge, play with it a bit and make sure its in right, with tab pulled. another tool is monitoring how long it tries to and the Cyan, does it attempt to restore it' levels for about 90 seconds or is it immediately tell you there's a cyan issue? Can you hear the motor and toner bottle turning? It should tell you "adding Cyan Toner" or even "Check Cyan Cartridge" worst case scenario you call Toshiba business Solutions and they vacuum it all out and do some adjustments......could be a good thing With Toshiba you get a lot of bang for your buck, meaning: a service call is good every once in a while. Your 4511 is a work horse you won't regret $pending for service. ~~~~~> SC
Usualy white lines are a signal for you that is time to replace a toner cartirdge. Your machine may inform you that you need to replace a toner cartridge, but sometimes the toner levels are low and the machine doesn't indicate that. Another thing that you may try is to clean all toner cartridges using each corona wire. If you need to replace your toner cartridge check this easy and helpful way to replace toner cartridge.
This machine (Sharp AL 1530CS) is a black and white printer/copier but can Scan (not print) in colour. It only has a black toner so will never print in colour...sorry
Check your settings for your printer software program, change it to black and white, and then you will need to change it back to color, if you want to print in color.
That's a process problem with that machine.
May require a service call .ON and OFF is pretty much all a customer can do and wait for it to setup. NOTE: The problem occurs because of the trickle development system in the machine, making extended lengths of black and white copies / prints does not allow the black developer housing to purge itself of excess waste Toner (Dry Ink) and Developer. There are two solutions for the problem:
Make 1,000 copies / prints of a black and white job, then make 150 copies / prints of full color. Continue making 1,000 copies / prints of the black and white job, then 150 full color, and so on, until the entire black and white job is complete.
Make extended jobs in groups of 100 by making 100 copies / prints of the black and white job, then allowing the machine to cycle down (return to 'Ready') and making the next 100 copies / prints. Continue in this pattern until the entire black and white job is complete.

Black toner problem.Probably You have low toner sensor defect.
But try first to vacuum and clean black toner dispenser.You must vacuum whole path wich is used to transport black toner to developer unit.Then if printing B/W print only, you must print 10 full color sheets every 100 copies.
