The product must pause for each page to be formatted before it prints. Complex pages take more time 
to format, resulting in reduced print speed. However, most jobs print at full engine speed (35 ppm on 
Letter-size media or 33 ppm on A4-size media).
●
Media size
Legal-size media reduces print speed because it is longer than the standard Letter- or A4–size media. A 
reduce print speed is used when printing on narrow media to prevent the edges of the fuser from 
overheating.
●
Media mode
Some media types require a reduced print speed to achieve maximum print quality on that media. For 
example, glossy, heavy, and specialty media (for example, envelopes or photos) require a reduced print 
speed. To maximize the print speed for special media types, ensure that you select the correct media 
type in the print driver.
●
Product temperature
To prevent product damage, print speed is reduced if the product reaches a specific internal 
temperature (thermal slow down). The starting temperature of the product, ambient environment 
temperature, and the print job size effect the number of pages that can be printed before the product 
reduces the print speed. Thermal slow down reduces print speed by printing four pages and then 
pausing for an amount of time before printing continues.
●
Other print speed reduction factors
Other factors (especially during large print jobs) that can cause reduced print speeds include:
◦
Density control sequence; occurs every 150 pages and takes about 120 seconds.
The product does not print or it prints slowly
The product does not print
If the product does not print at all, try the following solutions.
1. Make sure the product is turned on and that the control panel indicates it is ready.
●
If the control panel does not indicate the product is ready, turn the product off and then on again.
●
If the control panel indicates the product is ready, try sending the job again.
2. If the control panel indicates the product has an error, resolve the error and then try sending the job 
again.
3. Make sure the cables are all connected correctly. If the product is connected to a network, check the 
following items:
●
Check the light next to the network connection on the product. If the network is active, the light is 
green.
●
Make sure that you are using a network cable and not a phone cord to connect to the network.
●
Make sure the network router, hub, or switch is turned on and that it is working correctly.
4. Install the HP software from the CD that came with the product. Using generic printer drivers can cause 
delays clearing jobs from the print queue.
