Troubleshooting Common KIP Print Issues: Tips & FixesLarge-format KIP printers are workhorses in architecture, engineering, construction, and print shops. When they work well, they save time and deliver crisp, accurate plots and copies. When problems arise, they can slow whole projects. This guide walks through the most common KIP print issues, how to diagnose them, and practical fixes to get your system back to reliable operation.
1. Print Quality Problems
Common symptoms: streaks, banding, faded prints, uneven density, ghosting.
Causes and fixes:
- Dirty or damaged imaging components — Clean the printhead, fuser, and scanner glass per the KIP service manual. Use lint-free cloths and manufacturer-recommended cleaners. Inspect for physical damage; replace parts if worn.
- Low or contaminated toner — Replace toner cartridges with genuine KIP supplies. If toner appears clumped or contaminated, run a toner shake (if supported) or replace the cartridge.
- Incorrect print driver or settings — Ensure the driver matches your KIP model. Check resolution, media type, and density settings. For fine line work, use higher resolution settings.
- Worn developer or drum units — If prints show repeating patterns or declining quality across pages, inspect and replace developer units or drums as per maintenance schedule.
- Humidity and media issues — Store paper in a controlled environment; high humidity can cause cockling and uneven toner transfer. Use media specified for your KIP model.
2. Paper Jams and Feed Errors
Common symptoms: frequent jams, misfeeds, skewed prints.
Causes and fixes:
- Incorrect paper type or loading — Verify media size, weight, and feed orientation. Re-load rolls evenly, ensuring the core is seated properly.
- Worn feed rollers — Inspect and clean feed rollers; replace if glazed or damaged.
- Debris in path — Remove scraps, staples, or labels from the paper path. Power down before reaching inside.
- Improper tension or core adapters — Confirm roll tension is correct and core adapters match the roll diameter.
- Software spooler conflicts — Clear the print queue and restart the KIP and the host computer. Update firmware and drivers.
3. Network and Communication Issues
Common symptoms: unable to find KIP on network, slow job transfer, jobs stuck in queue.
Causes and fixes:
- IP address conflicts or incorrect settings — Verify the printer’s IP address, subnet mask, and gateway in the KIP control panel. Use static IPs for reliability, or reserve DHCP addresses.
- Firewall or port blocking — Ensure required ports (e.g., 80, 515, 9100, and any KIP-specific ports) are open between clients and the KIP. Temporarily disable firewalls for testing.
- Driver or protocol mismatch — Use KIP-recommended protocols (RAW/9100, LPR, or Windows SMB where applicable). Install the correct KIP driver version on client machines.
- Network congestion or slow switches — Test transfer speeds and consider connecting the KIP to a dedicated VLAN or a higher-bandwidth switch port.
- Firmware compatibility — Update printer firmware and check release notes for network-related fixes.
4. Calibration, Color, and Copy Registration Issues
Common symptoms: misaligned copies, inaccurate colors, registration drift between prints.
Causes and fixes:
- Calibration needed — Run the KIP’s built-in calibration routines for density, registration, and color. Regularly schedule calibrations.
- Dirty scanner or sensors — Clean scanner glass, sensors, and rollers. Dust can skew registration and color reading.
- Mismatched media profiles — Use correct media profiles and ICC profiles for color-critical output. Verify the media setting in the driver matches the loaded stock.
- Mechanical wear — Worn guide rails or belts can affect registration. Inspect and replace as necessary.
- Environmental changes — Large temperature/humidity swings can affect color stability; let new media acclimate to the room before printing.
5. Mechanical Noises and Hardware Errors
Common symptoms: grinding, scraping noises, error codes on the control panel.
Causes and fixes:
- Foreign object in mechanism — Power down and inspect for paper clips, labels, or torn paper. Remove anything found and restart.
- Worn gears, bearings, or belts — Unusual noises often indicate wear. Contact KIP support or a qualified technician for part replacement.
- Improperly installed parts — Ensure all covers, cartridges, and modules are seated correctly. Reseat modules if necessary.
- Overloaded or improper duty cycles — Verify your workload aligns with the model’s rated duty cycle. Distribute large jobs to avoid overheating or overuse.
6. Error Codes and Messages
Common symptoms: specific error codes, job aborts, warnings.
Steps to resolve:
- Consult the manual — Look up the exact error code in the KIP user/service manual for targeted steps.
- Reboot and retry — Power cycle the printer; many transient errors clear with a restart.
- Check consumables and sensors — Error codes often point to low toner, tray empty, or sensor blockage—verify and replace/clear as needed.
- Update firmware — Some error codes are due to bugs fixed in firmware updates; check KIP release notes.
- Contact support with logs — If the error persists, gather system logs and contact KIP support or an authorized service technician.
7. Slow Printing or Processing Delays
Common symptoms: long time to rasterize or print, slow spool times.
Causes and fixes:
- High-resolution or complex files — Raster-heavy PDFs, large TIFFs, or layered CAD files take longer. Flatten layers, simplify files, or rasterize selectively.
- Insufficient memory or storage — Check the KIP’s memory usage. Add or clear internal storage, or use a print server with more RAM.
- Drivers sending inefficient data formats — Use postscript or optimized driver settings. Turn on driver options like “send as image” only when necessary.
- Network latency — Move large files over fast wired connections or compress files before sending.
- Spooler or workstation bottlenecks — Restart the workstation spooler, update drivers, or use a dedicated print server.
8. Best Practices for Prevention
- Use genuine KIP consumables and recommended media.
- Keep firmware and drivers current.
- Schedule regular maintenance: cleaning, calibration, and inspection of rollers/drums.
- Train staff on proper media loading, error-code basics, and safe handling.
- Maintain an inventory of common spare parts (feed rollers, fusers, toner cartridges).
9. When to Call a Technician
Call for service when:
- Replacing a component is beyond your team’s comfort or warranty terms.
- Mechanical noises persist after cleaning and inspection.
- Frequent recurring errors or hardware faults appear in logs.
- Firmware updates fail or leave the unit unstable.
References and further reading:
- KIP user and service manuals for model-specific procedures.
- Manufacturer support articles for firmware and known issues.
