A field technician is troubleshooting distinct printing issues across various department printer types in an organization. Match each reported printer symptom on the left to its most likely root cause or resolution on the right.
- A point-of-sale thermal receipt printer feeds paper correctly but produces completely blank receipts.Thermal paper roll loaded upside down or backwards in the paper tray.
- A departmental monochrome laser printer outputs continuous dark vertical lines running down every page.Scratched or damaged photosensitive imaging drum.
- A desktop color inkjet printer outputs faint, streaky images with missing color lines after being unused for several weeks.Dried ink causing clogged printhead nozzles.
- A warehouse impact dot-matrix printer produces faint, faded text across all pages of multi-part carbonless forms.Depleted fabric ink ribbon cartridge requiring replacement.
Cevap
1. Thermal receipt printer blank output matches Thermal paper roll loaded upside down or backwards. 2. Laser printer continuous dark vertical lines matches Scratched or damaged photosensitive imaging drum. 3. Inkjet printer faint/streaky output matches Dried ink causing clogged printhead nozzles. 4. Dot-matrix printer faint text on multi-part forms matches Depleted fabric ink ribbon cartridge requiring replacement.
Each printer technology exhibits distinctive failure symptoms: reversed thermal paper prevents heat-activated dye reaction; drum scratches cause continuous laser vertical lines; dried liquid ink clogs inkjet printhead nozzles; and depleted fabric ribbons cause faint dot-matrix impact printing across multi-part forms.
