Page Protection
If printed images are too complex to print, the printer may print a partical image on the paper. If this occurs, the printer loses print data and indicates the “print overrun error” by printing the error report. (See the chapter 6 “ALARM INDICATION AT A GLANCE”.)
The page protection feature allows the printer to create the image to be printed in memory before physically moving the paper through the printer. Therefore, page protection may eliminate the "PRINT OVERRUN" error.
The setting "AUTO" does not require the additional memory and it automatically uses page protection only when it is necessary. Occationally, when AUTO page protection is on, processing complex print data may be slightly delayed.
✒Note:
When you set this setting to A4, Letter or Legal, the following capacity of memory is required.
| 300 dpi | 600 dpi | |
Letter/A4 | 2 Mbytes | 6 | Mbytes |
Legal | 3 Mbytes | 6 | MBytes |
If your printer does not have enough memory for page protection, your document may be printed at 300 dpi.
You can set this function through the followings.
∙The supplied printer driver for Windows 3.1
∙The supplied RPC program for DOS
