We wouldn't say it's common, Kevin, but it can happen, especially in older machines where the heating element may have burned/be burning out. According to Zojirushi's troubleshooting guide (found on pg. 31 of your manual), they suggest decreasing the amount of sugar in the recipe by 1Tbsp (sugar leads to browning), making sure the correct course was chosen, and/or removing the bread from the baking pan immediately upon completion of the cycle. If you continue to experience problems, we'd recommend contacting Zojirushi's customer service team directly—contact info can also be found in your manual. Mollie@KAF
