The —— —— ——– are usually on a small circuit board that contains all circuitry to run the step motors the way the printer needs them to work .P457
Printer control circuit.
Are the printer control circuits also responsible for monitoring the health of the computer and reporting that information back to the PC. T/F P457
true
The last set of circuits the printer uses is the —— ——-.P457
Power circuits.
A ——— ,in the case ,takes the 110v AC current and charges it to 12v DC.P457
Transformer.
T?F. Are there a set of steps the printer must follow to put the data onto the page being printer?P457
True
Laser printers and inkjet printers are referred to as —— ——– because they receive their print job one page at a time rather than receiving instructions one line at a time.P458
Page printers..
EP is ?P458
Electrophotographic.
What two major types of page printers that use the electrophotographic print processes?P458
The first uses a laser to scan the image, and the second uses a light emitting diodes (LED) to create the on the drum.
What EP process contains nine standard asseblies?P459
Toner cartridge,laser scanner, high voltage power supply,paper transport assembly,transfer corona, fusing assembly ,printer controller circuitry, and ozone filter.
The toner cartridge also contains what?P459
EP print drum
T/f. Does the drum assembly contain a cleaning blade,and what does it do ?P459
True.. it continuously the used toner off the photosensitive drum to keep it safe.
T/F. Does exposing a photosensitive drum to dust and light damage it/ light ?P459
True
Y/N Should you ever ship a printer anywhere with a toner cartridge installed?P460
no
T/F. Laser light is damaging to human eyes?P460
True..
HVPS is/P460
high voltage power supply
DCPS is?P461
DC power supply.
The —– can hurt or kill you if you are inside a laser printer and don’t know what you’re doing?P461
Hvps
The first type of roller found in most laser printers is the —– —– or —— ——?P461
Feed roller.,Paper pickup roller
There are actually —– registration rollers,which work together?P461
two
both of these rollers are operated with a special electric motor know as an —— ——- ——-?P462
Electronic stepper motor.
How does the toner get from the photosensitive drum on to t he paper?P462
Threw the transfer corona assembly…
The transfer corona assembly is a —— —— —— —— that drains away the charge imparted to the paper by the coronaP462
STATIC CHARGE ELIMINATOR STRIP.
what are six major steps for the Ep print process?P464
Processing, charging,exposing(writing),developing transferring, fusing, and cleaning.
The fuser is made out of three main parts?P463
Halogen heating lamp,teflon coated aluminum fusing roller, and a rubberized pressure roller.
