How to put paper in dot matrix printer
As a classic tool in office equipment, dot matrix printers are gradually being replaced by laser and inkjet printers, but they are still widely used in specific scenarios (such as multi-part bill printing). Correct paper placement is a key step to ensure printing results. This article will introduce in detail the paper placement method of dot matrix printers, and attach relevant data comparisons.
1. Steps to put paper in dot matrix printer
1.Preparation: Turn off the printer and check if the paper type matches (such as continuous paper or cut-sheet paper).
2.paper placement:
- Continuous paper: Align the holes on both sides of the paper with the tractor teeth of the printer, and adjust the fixed positions of the left and right baffles.
- Single-page paper: Put it into the paper input slot, making sure the paper is aligned with the guide rails to avoid skewing.
3.Adjust paper thickness lever: Adjust the thickness control lever on the side of the printer (usually 1-4 levels) according to the paper thickness.
4.Power on test: Start the printer and confirm whether paper feeding is smooth through self-test or printing a test page.
| Paper type | Applicable scenarios | Key points for putting paper |
|---|---|---|
| Continuous paper (with holes) | Invoice and report printing | Align perforations, disable cut-sheet mode |
| single page | Ordinary document printing | Close to the guide rail, adjust the thickness lever to the low position |
| multi-layer carbon paper | Contract, receipt | Adjust the thickness lever to the highest setting |
2. Common problems and solutions
| Problem phenomenon | Possible reasons | solution |
|---|---|---|
| paper jam | Paper feed is skewed or thickness lever is set improperly | Realign the paper and adjust the thickness |
| Blurred printing | The paper is too thick or the ribbon is aged | Replace the ribbon or reduce the paper thickness |
| Paper not fed | Paper sensor failure | Clean the sensor or contact after-sales service |
3. Maintenance recommendations for dot matrix printers
1.Regular cleaning: Clean the print head and roller with alcohol wipes monthly.
2.Ribbon replacement: When the printing color becomes lighter, replace the ribbon in time (usually the life span is about 3 million characters).
3.Environmental requirements: Avoid high temperature and humid environments, and pay attention to dust when storing paper.
| maintenance items | Frequency | Things to note |
|---|---|---|
| Ribbon replacement | By usage | Requires power off operation |
| Drum cleaning | 1 time per month | Disable sharp tools |
| Mechanical lubrication | 1 time per year | Use special lubricants |
4. Comparison of technical parameters (mainstream dot matrix printers)
| Brand model | Maximum paper width | Paper feeding method | Thickness adjustment gear |
|---|---|---|---|
| EPSON LQ-610K | 257mm | Front/rear feeding | 6th gear |
| Deshi DS-720 | 297mm | Chain feed | 8 gears |
| Fujitsu DPK750 | 381mm | Flat push type | 4th gear |
Through the above structured instructions, users can quickly master the paper placement skills of dot matrix printers. Proper paper installation not only improves printing efficiency, but also extends the service life of the printer. If you encounter complex problems, it is recommended to refer to the equipment manual or contact professional technicians.
