Review device error codes
- B.
Identify symptoms
- C.
Print a test page
- D.
Increase memory
Correct Answer(s)
A. Review device error codes
B. Identify symptoms
C. Print a test pageExplanation
Reviewing device error codes, identifying symptoms, and printing a test page are all considered troubleshooting tools and techniques for printers. Reviewing device error codes helps to identify specific issues or malfunctions that may be occurring. Identifying symptoms involves recognizing any unusual behavior or patterns that may indicate a problem with the printer. Printing a test page can help to determine if the printer is functioning properly and if there are any issues with print quality or alignment. Increasing memory, on the other hand, is not a troubleshooting tool or technique for printers, as it does not directly address or resolve any printer-related issues.Rate this question:

What happens if a page you print on a laser printer requires more memory thanthe printer has installed?
- A.
The printer will notify you that you need to free some resources.
- B.
The printer will continue to work but at a slower than normal pace.
- C.
The printer will try to print the page but will stop before the job is finished.
- D.
It will use hard drive space to print.
Correct Answer
B. The printer will continue to work but at a slower than normal pace.Explanation
If a page requires more memory than the printer has installed, the printer will still continue to work but at a slower than normal pace. This is because the printer will need to process the data in smaller chunks or pause frequently to free up memory. As a result, the printing speed will be significantly reduced. However, the printer will still attempt to complete the printing job, albeit at a slower pace.Rate this question:
