Laser Printing Flashcards
What is the first step of laser printing?
Processing
What is the second step of laser printing?
Charging
What is the third step to laser printing?
Exposing
What is the fourth step to laser printing?
Developing
What is the fifth step to laser printing?
Transferring
What is the sixth step to laser printing?
Fusing
What is the seventh step to laser printing?
Cleaning
What enables the printer to que up multiple print jobs?
Print spooler
What is the first potential bottleneck in the processing phase?
The first print job, if it’s big
What kind of image does the laser imaging unit “paint” onto the photosensitive drum?
Raster image
What is the name of the chip that translates the Raster image into commands to the laser?
Raster image processor (RIP)
If you get a MEM OVERFLOW error, what fix is least likely to work?
A) reduce resolution
B) restart the printer
C) add more printer ram
B) restart the printer
If you get a MEM OVERFLOW error, what fix is least likely to work?
A) clean the drum
B) try smaller graphics
C) turn off ret
A) clean the drum
Does adding more memory fix every memory problem?
No
If a laser printer is 2400 x 600 dpi, what does 2400 mean?
How fine a focus the laser can achieve
If a laser printer is 2400 x 600 dpi, what does 600 mean?
The smallest increment by which the drum can be turned.
What does resolution enhancement technology (ret) do?
Adds smaller dots to smooth out jagged characters
What applies a negative charge to the drum?
Primary corona or primary charge roller
What does the laser do?
Makes a positive image on the drum
What happens in the developing stage?
Toner gets put on the drum
What is the most prominent thing that happens in the fusing stage?
The toner from the drum gets fused to the paper
What rollers are involved when toner gets fused to the paper?
a heated roller and a pressure roller
What is the last step in the fusing stage?
A static charge eliminator removes the paper’s positive charge.
What usually cleans the drum?
A rubber cleaning blade
If random black spots and streaks appear on a page, what does that likely mean?
The drum didn’t get cleaned properly
What is likely the problem if a mark gets printed on every page?
The drum is damaged and thus cannot be cleaned properly
