Managing memory

Many applications collate documents by repeatedly sending the file to the printer. As a 
result, the printer must process each print job until the correct number of copies has 
printed. This requires additional time since the printer must process the same pages 
repeatedly. By using the Collation setting, the printer processes the file only once, saves 
the file in printer memory, and prints the multiple copies. This saves processing time for 
the printer and for the application, and may reduce overall printing time.

For Collation to work effectively, your software application must recognize this printer fea-
ture and not send the job to the printer multiple times. Your application must also let you 
specify the number of copies needed or let you use the printer default setting for Copies.

Select Collation from the operator panel or from the printer driver. For best results, select 
Collated in the printer driver and set the number of copies to one. In your application, 
select Uncollated (if the option is available) and then select the number of copies you 
want.

If the job exceeds the memory capacity of your printer, you receive an

message. Press 

 to clear the message. The printer collates the remaining 

pages in memory. If you reset the printer, the printer discards the job.

For more information on using Collation, see “Collating print jobs” on page 111. For 
details on the Collation setting, see page 41.

PostScript 3 emulation and PCL emulation can be active at the same time. Resource 
Save preserves any data stored for each printer language while switching quickly 
between the languages. This is achieved without preallocating printer memory for each 
language. 

For example, let’s say the Optra W810 is being used as a network printer. User A has 
downloaded some fonts and forms in PCL emulation. User B then sends a PostScript 
emulation job to the printer. When User A wants to print again in PCL emulation using the 
forms and fonts previously downloaded, they are still available for the job. With Resource 
Save on, switching printer languages does not affect the availability of language-specific 
resources. In printer environments without a Resource Save function, User A would have 
to download the fonts and forms again, since the switch to PostScript emulation would 
have deleted all of the PCL emulation resources.

When Resource Save is set to Off, the printer still saves resources after language 
switches, but only until the memory being used is required for another printer function.
