Scanning PDFs is a pain, but it’s often a necessary part of doing business. If you work in an office, someone has most likely trained you in the ways of PDF. With more entrepreneurs than ever striking out on their own, however, you might need a helping hand. And let’s be real: There’s nothing as frustrating as figuring out how to scan multiple pages into one PDF document.

Unfortunately, unless you have purchased a scanner with an automatic document feeder, most scanner models make it complicated to scan multiple pages into a single document. Each system tends to have their own quirks, requiring you to learn a particular process depending on what you buy.

Take HP, for example. If you’re using scanner without an automatic feeder, you need to go to HP Scan, select Save as PDF to scan your first document. Then when you load the next page or photo to your scanner tray, click the “Page+” button (usually a page with a plus sign in it) to scan the next time. Repeat this step until all your pages are scanned, then press “Save.”

Those instructions are just for one brand of printer. If you move around or use different office sites, it can become complicated learning all of the nuances of each machine. That’s why we recommend you scan your documents individually, and then just piece them together using a PDF app.

Which PDF app? Well, if you read our breakdown of the best free PDF editing apps, you might already have an idea.

There are too many variations of how these products work to cover them all here. However, with some Googling, you can easily find the solution to your particular scanner’s quirks.
