How long does the printer wait for another le?
So that the printer can make the best nest possible, it waits after a le has been received to check whether a
subsequent page will nest with it or with pages already in the queue. This waiting period is the nest wait time;
the factory default nest wait time is 2 minutes. This means that the printer waits for up to 2 minutes after the
last le is received before printing the nal nest. You can change this waiting time from the printer's front panel:
tap , then Job management > Nest options, and select the wait time. The available range is 1 to 99
minutes.
While the printer is waiting for nesting to time out, it displays the remaining time on the front panel, and in the
Embedded Web Server’s Job queue tab.
Manage nesting in the Embedded Web Server
You can manage the nesting of your jobs in the Embedded Web Server’s Job queue tab.
The Up next box shows the jobs that are waiting in the queue; the Now printing box shows the job or jobs that
are currently printing.
In between them is the nesting box:
If you click the icon in the nesting box, the jobs in the Up next box will be nested; and the nesting box will
display a countdown to the time when they will start printing. You can adjust this time: see How long does the
printer wait for another le? on page 72.
When the printer is printing nested jobs, the Now printing box has a Cancel button to cancel all the nested jobs
that are currently printing.
Use ink economically
Here are some recommendations for making economical use of ink:
● For draft prints, use plain paper and move the print-quality slider to the left end of the scale ('Speed'). For
further economy, select custom print quality options, then select Fast and Economode.
● Clean the printheads only when needed, and clean only those printheads that need cleaning. Cleaning the
printheads can be useful, but it uses a small amount of ink.
● Leave the printer permanently turned on so that it can maintain the printheads in good condition
automatically. This regular printhead maintenance uses a small amount of ink. However, if it is not done,
the printer may need to use much more ink later to restore the health of the printheads.
● Wide prints make more eicient use of ink than narrow prints, because printhead maintenance uses some
ink, and its frequency is related to the number of passes made by the printheads. Therefore, nesting jobs
can save ink as well as saving paper (see Nest jobs to save roll paper on page 70).
