Select when to print a job
NOTE: The When To Start Printing options cannot be used with PostScript jobs.
You can select at what point you want to print a job in the queue. Tap , then Job management > When to
start printing.
There are three options you can select:
● When After Processing is selected, the printer waits until the whole page has been processed and then it
starts to print. This is the slowest setting but ensures the best print quality in large or complex prints.
● When Immediately is selected, the printer prints the page as it is processed. This is the quickest setting, but
the printer may stop halfway through a print to process data. This setting is not recommended for complex
images with dense color.
● When Optimized is selected (this is the default setting), the printer calculates the best time to begin printing
the page. It is usually the best compromise between the After Processing and Immediately settings.
See job details
Tap the name of the job to show its details, including information about status, pages, copies, total, and preview.
Scroll down as necessary to see all of the information.
By tapping the thumbnail, you can navigate over all pages of the job. Tap to show or hide the toolbar. From
there you can zoom in and out and see more information about each page.
In an active queue, the job you are printing appears in the middle of the queue, with printed jobs below and jobs
to be printed above.
Roll policies
If two rolls are loaded, both of which are suitable for the job, the roll is chosen according to your preferences.
At the front panel, tap , then , then .
Alternatively, tap , then Job management > Roll policies.
● Increase productivity: To increase the productivity of the printer.
–
Job autorotation: The printer can rotate a job automatically in order to save paper.
● Automatic roll selection: When the job arrives with the roll not dened, the printer selects the rolls
according to the following settings.
– Roll width selection: The printer can be more or less restrictive when selecting the roll width on which
to print. You can select to print on the same width only (each page prints on a roll with same width as
the page) or to print on the same width or wider (each page prints on roll with same width as the page
or wider).
– Avoid printing on a wider roll: Avoid switching to a wider roll when the dened rolls are depleted. Only
applies when Roll width selection is Print on same width or wider.
