Common Causes of “Printing Limit Exceeded” Errors on UV Flatbed Printers

During the printing process, UV flatbed printers may occasionally display a “printing limit exceeded” error. This issue is typically caused by one of the following six factors: poor encoder contact, damaged encoder, misaligned grating strip, oversized image array, incorrect printing direction, or damaged software.

1. Poor Encoder Contact

Solution: 

Check whether the encoder interface is loose; if so, tighten it securely.

2. Damaged Encoder

Solution: 

Contact the original printer manufacturer to request a replacement encoder.

Note: Encoders vary across different printer models, so make sure to use the correct type.

3. Misaligned Grating Strip

Solution: 

Recalibrate the grating strip to its correct position.

If the grating strip is damaged, replace it with a new one.

4. Image Array Exceeds Limit

Solution: 

In Photoshop or the image design software, reduce the image size so it stays within the allowable array range.

5. Incorrect Printing Direction

Solution: 

Adjust the incorrect printing direction value in the printer control software.

6. Damaged Printing Software

Solution: 

Reinstall the printer control software.

Software corruption is often caused by antivirus programs falsely flagging the software as malicious — be sure to add the software to the whitelist.

Additionally, avoid inserting USB drives from unknown sources, as they may contain viruses that can damage the UV printer’s control software.
