Straight-through paper path
Course ILT
Curved paper path
Course ILT
Inkject photo printers
 Don’t hold up as long as traditional,
chemically produced dark-room
photos
 Special paper required
 Use regular paper = lower quality
prints
 Can print on non-paper items
Course ILT
Printing on non-paper surface

Inkjet printer installation
 Connect via USB
 Windows autodetects and installs drivers
 Can install additional software from
manufacturer

Inkjet communications interfaces
Course ILT
Parallel interface
USB interface
Course ILT
Configure connection type
 SCSI — assign a unique device ID
 Parallel — Specify the correct LPT
port
 Serial — Specify the correct COM port
Course ILT
Parallel port in Device Manager
Course ILT
Installing an inkjet printer
1. Connect the printer to a computer
using the correct interface
2. Plug it in
3. Power it up
4. Windows will likely recognize you’ve
connected a new device and install
drivers for it automatically
5. If drivers aren’t installed
automatically, you can do it manually
using the materials that shipped with
the printer
Course ILT
Activity B-2
Installing an inkjet printer
Inkjet printer maintenance
Course ILT
 Consumables
– Paper
– Ink levels
 Color matching
 Environment
 Safety
Course ILT
Optimization
 Paper trays/orientation
 Print spool settings
Course ILT
Troubleshooting
 Acquire information about the problem
 Simplify by removing any non-critical
components, shut down unnecessary
running programs, and disconnect from the
Internet or network.
 Implement by identifying probable causes
and implementing potential solutions one at
a time.
 Document the error symptoms, the
components you removed from the
computer, and the solutions you tried and
whether they were successful.
