Abstract: An information processing apparatus includes a first CPU, a second CPU, a first nonvolatile memory that stores a boot program to be executed by the first CPU at a time of start-up, and a second nonvolatile memory that stores a first boot program and a second boot program for verifying a program. The first CPU determines whether or not a verification method is set in the first nonvolatile memory, and if not, the first CPU executes the first boot program, and writes the setting of the verification method to the second nonvolatile memory. If the verification method is set, the first CPU executes the second boot program in accordance with the setting, and when the processing of the second boot program is normally ended, the second CPU starts up the information processing apparatus.

Abstract: In an image forming apparatus, a CPU can perform in a normal mode and a low mode in which a photoconductive drum rotates at a rate m/n times the rotational rate in the normal mode, and lower than the rotational rate in the normal mode. In the low mode, the CPU causes a synchronizing signal generation portion to generate a line synchronizing signal at a cycle 1/m times the cycle of the line synchronizing signal generated in the normal mode, and causes a chip data conversion portion to transmit, to an exposure head, the same image data signal m times and transmit, to the exposure head, an image data signal that brings a light-emitting portion into no light emission n-m times, in synchronization with n number of line synchronizing signals.

Abstract: An information processing apparatus capable of preventing erroneous connection at a time of connection using cables without deteriorating versatility. The information processing apparatus is communicable with an external device via two cables. A first connector is connected to one of the two cables and has terminals, which include a first terminal that is arranged at a first position and receives a predetermined signal output according to start-up of the external device. A second connector of a same shape as the first connector is connected to another of the two cables and that has terminals, which are identical to the terminals of the first connector in number and arrangement and include a second terminal that is not used to output a signal and is arranged at a position corresponding to the first terminal. A controller notifies of an error through a notification device when the second terminal receives the predetermined signal.
