Test V5.1c | Printer

Originally designed by the community (with roots tracing back to early RepRap days), v5.1c is a multi-challenge test print. It combines:

All in one small model — usually printing in under an hour on a standard 0.4mm nozzle. printer test v5.1c

A series of horizontal and vertical lines drawn at exactly 1/300th of an inch. For standard 600 DPI printers, these lines should be distinct. Bridging (where the ink fills the gap between lines) indicates ink pooling—too much ink being laid down. Broken lines indicate missing nozzles.

Once you have printed v5.1c, you need to read the evidence. Here is a troubleshooting guide based on specific defects.

| Observed Defect | Likely Cause | Solution | |---------------------|------------------|---------------| | White horizontal lines across all color bands | Clogged nozzles (specific to one color) | Run 1-2 cleaning cycles. If persists, use a print head cleaning solution. | | Periodic vertical banding (every 1 inch) | Dirty paper feed roller or worn encoder strip | Clean rollers with isopropyl alcohol; check encoder strip for dust. | | Ghosted text (shadow to the right of letters) | Bi-directional misalignment | Run printer’s built-in alignment utility (usually in driver maintenance tab). | | Colors look muddy (e.g., cyan appears teal) | Failing color management or low ink | Re-run with color management off. If still muddy, replace cartridges. | | Missing fine dots in same position on each band | Dead nozzle (electronic failure) | Try deep cleaning. If no improvement, head replacement is needed. | | Star burst target shows wavy spokes | Paper advance mechanism slipping | Calibrate paper feed (service menu on some printers). |
