Certain 
 
PCL Menu
 
 and 
 
PostScript Menu
 
 options affect the 
printer’s performance and memory usage, as described in 
 
“PCL Menu” (page 3-15)
 
 and 
 
“PostScript Menu” (page 3-29)
 
Figure 3.25 provides more detailed information on these 
options.

Description
 
Page Protection
 
PCL Menu
 
 (page 3-26)
When a page is particularly complex with graphics or dense text, the printer 
may not be able to process it rapidly enough to keep up with normal 
printing operations. Data may be lost or one page may be split on multiple 
pages.
 
Page protection
 
 is a technique that reserves memory to ensure the entire 
page can be created and printed before the actual printing process. The 
trade-off in performance is matched by the certainty that an entire complex 
page may be printed.
 
Page Protection
 
 is related to 
 
Resolution
 
 (page 3-27 for PCL, page 3-35 
for PostScript, and page 3-68) since the amount of memory needed for a 
page depends on its resolution. The higher the resolution, the more 
memory needed. See 
 
Figure 3.26 (page 3-69)
 
 for memory requirements.
Your software application may change the 
 
Page Protection
 
 level (e.g., 
from 
 
Legal
 
 to 
 
Letter
 
). When that occurs, the printer’s memory is 
reconfigured. Downloaded fonts and macros may be cleared from memory 
unless 
 
State Saving
 
 (page 3-28 for PCL, page 3-36 for PostScript, and 
page 3-68) is set. 
If any request for memory cannot be satisfied, you will be notified on the 
Control Panel.
If you frequently see the following error message
 
Page Too Complex
 
you may want to set 
 
Page Protection
 
 to be able to print the entire page. 
Otherwise, if you do not see frequent warning messages, set 
 
Page 
Protection
 
 
 
Off
 
.
