1Turn off the HP OfficeJet Pro, remove the power cord, and then raise the document cover.
2Clean the glass with a soft cloth or sponge slightly moistened with warm water and a mild soap or detergent. You may also use glass cleaner.
CAUTION Do not use abrasives, acetone, benzene, or carbon tetrachloride on the glass; these can damage the glass. Do not place liquids directly on the glass. They may seep under it and damage your HP OfficeJet Pro.
3Rinse the soft cloth or sponge with clean water, wring out excess water, and wipe the remaining soap or detergent off the glass.
4Dry the glass with a chamois or cellulose sponge to prevent spotting. If soap or detergent does not clean the glass sufficiently, you can use isopropyl alcohol as a cleaning agent.
