Suggested Remedy

On the printer, change the Plain Paper Weight setting to Heavy. You will find this setting under the Paper Menu.

For card stock and labels, simply change the Paper Type to Card Stockor Labels.These two settings automatically adjust printer temperatures for heavier types of media. It is not recommended that you set Paper Type to Plain. However, you can set the Card Stock and Label Weight to Heavy if necessary.


The recommended range for what is considered normal weight paper is 20 to 24 lbs. Printing on 'heavy weight' media does increase the potential for toner to not completely adhere to the page. This results in print quality issues.
